# Integer comparison

(Redirected from Comparing two integers)
Integer comparison
You are encouraged to solve this task according to the task description, using any language you may know.

Basic Data Operation
This is a basic data operation. It represents a fundamental action on a basic data type.

You may see other such operations in the Basic Data Operations category, or:

Integer Operations
Arithmetic | Comparison

Boolean Operations
Bitwise | Logical

String Operations
Concatenation | Interpolation | Comparison | Matching

Memory Operations

Get two integers from the user.

Then,   display a message if the first integer is:

•   less than,
•   equal to,   or
•   greater than

the second integer.

Test the condition   for each case separately,   so that   all three comparison operators are used   in the code.

## 11l

```V a = Int(input(‘Enter value of a: ’))
V b = Int(input(‘Enter value of b: ’))

I a < b
print(‘a is less than b’)
I a > b
print(‘a is greater than b’)
I a == b
print(‘a is equal to b’)```

## 360 Assembly

Input is done by a standard register 1 pointed parameter list.

```INTCOMP  PROLOG

END```

## 6502 Assembly

Code is called as a subroutine (i.e. JSR Compare). Specific OS/hardware routines for user input and printing are left unimplemented. It should be noted that this is strictly an unsigned comparison.

```Compare		PHA			;push Accumulator onto stack
JSR GetUserInput	;routine not implemented
;integers to compare now in memory locations A and B
LDA A
CMP B			;sets flags as if a subtraction (a - b) had been carried out
BCC A_less_than_B	;branch if carry clear
BEQ A_equals_B		;branch if equal
;else A greater than B
JSR DisplayAGreaterThanB;routine not implemented
JMP Done
A_less_than_B:	JSR DisplayALessThanB	;routine not implemented
JMP Done
A_equals_B:	JSR DisplayAEqualsB	;routine not implemented
Done:		PLA			;restore Accumulator from stack
RTS			;return from subroutine```

## 68000 Assembly

The task of getting input from the user is much more difficult in assembly since it hasn't been done for you unlike nearly all other languages. So that part will be omitted to focus on the actual comparison.

In assembly, the only difference between a signed integer and an unsigned integer is the comparator(s) used to evaluate it. Therefore we have two different versions of this task.

### Unsigned Comparison

```Compare:
;integers to compare are in D0 and D1
CMP.L D1,D0
BCS .less ;D1 < D0
;else, carry clear, which implies greater than or equal to.
BNE .greater ;D1 > D0
;else, d1 = d0
LEA Equal,A0
JMP PrintString ;and use its RTS to return
.greater:
LEA GreaterThan,A0
JMP PrintString ;and use its RTS to return
.less:
LEA LessThan,A0
JMP PrintString ;and use its RTS to return

LessThan:
dc.b "second integer less than first",0
even
GreaterThan:
dc.b "second integer greater than first",0
even
Equal:
dc.b "both are equal",0
even
```

### Signed Comparison

```Compare:
;integers to compare are in D0 and D1
CMP.L D1,D0
BLT .less ;D1 < D0
;else, carry clear, which implies greater than or equal to.
BNE .greater ;D1 > D0
;else, d1 = d0
LEA Equal,A0
JMP PrintString ;and use its RTS to return
.greater:
LEA GreaterThan,A0
JMP PrintString ;and use its RTS to return
.less:
LEA LessThan,A0
JMP PrintString ;and use its RTS to return

LessThan:
dc.b "second integer less than first",0
even
GreaterThan:
dc.b "second integer greater than first",0
even
Equal:
dc.b "both are equal",0
even
```

## 8051 Assembly

Input/output is specific to hardware; this code assumes the integers are in registers a and b. There is only one comparison instruction to use: 'not equal'.

```compare:
push psw
cjne a, b, clt
; a == b
; implement code here
jmp compare_
clt:
jc lt
; a > b
; implement code here
jmp compare_
lt:
; a < b
; implement code here
compare_:
pop psw
ret
```

Testing for (a <= b) or (a >= b) can be performed by changing the jumps.

## 8th

The user would put the numbers on the stack and then invoke 'compare':

```: compare \ n m --
2dup n:= if "They are equal" . cr then
2dup n:< if "First less than second" . cr then
n:> if "First greater than second" . cr then ;
```

Alternatively one could use the "n:cmp" word

## AArch64 Assembly

Compare once (`cmp x0, x1`) and use conditional branching (`b.eq` and `b.gt`).

```.equ STDOUT, 1
.equ SVC_WRITE, 64
.equ SVC_EXIT, 93

.text
.global _start

_start:
stp x29, x30, [sp, -16]!
mov x0, #123
mov x1, #456
mov x29, sp
bl integer_compare // integer_compare(123, 456);
mov x0, #-123
mov x1, #-456
bl integer_compare // integer_compare(-123, -456);
mov x0, #123
mov x1, #123
bl integer_compare // integer_compare(123, 123);
ldp x29, x30, [sp], 16
mov x0, #0
b _exit // exit(0);

// void integer_compare(long long x, long long y) - compare two signed integers and print a message
integer_compare:
cmp x0, x1
mov x0, #STDOUT
b.eq 1f
b.gt 2f
// x < y
ldr x1, =msg_lt
mov x2, #17
b _write
1:	// x == y
ldr x1, =msg_eq
mov x2, #16
b _write
2:	// x > y
ldr x1, =msg_gt
mov x2, #20
b _write

msg_lt:
.ascii "x is less than y\n"
msg_eq:
.ascii "x is equal to y\n"
msg_gt:
.ascii "x is greater than y\n"
.align 4

//////////////// system call wrappers
// ssize_t _write(int fd, void *buf, size_t count)
_write:
stp x29, x30, [sp, -16]!
mov x8, #SVC_WRITE
mov x29, sp
svc #0
ldp x29, x30, [sp], 16
ret

// void _exit(int retval)
_exit:
mov x8, #SVC_EXIT
svc #0```

## ABAP

This works in ABAP version 7.40 and above. Note that empty input is evaluated to 0.

```report z_integer_comparison.

parameters: a type int4, b type int4.

data(comparison_result) = cond string(
when a < b " can be replaced by a lt b
then |{ a } is less than { b }|
when a = b " can be replaced by a eq b
then |{ a } is equal to { b }|
when a > b " can be replaced by a gt b
then |{ a } is greater than { b }| ).

write comparison_result.
```

## Action!

```PROC Main()
INT a,b

Print("Input value of a:") a=InputI()
Print("Input value of b:") b=InputI()

IF a<b THEN
PrintF("%I is less than %I%E",a,b)
FI
IF a>b THEN
PrintF("%I is greater than %I%E",a,b)
FI
IF a=b THEN
PrintF("%I is equal to %I%E",a,b)
FI
RETURN```
Output:
```Input value of a:123
Input value of b:4712
123 is less than 4712
```

```with Ada.Text_IO; use Ada.Text_IO;

procedure Compare_Ints is
A, B : Integer;
begin
Get(Item => A);
Get(Item => B);

-- Test for equality
if A = B then
Put_Line("A equals B");
end if;

-- Test For Less Than
if A < B then
Put_Line("A is less than B");
end if;

-- Test For Greater Than
if A > B then
Put_Line("A is greater than B");
end if;
end Compare_Ints;
```

## Aime

```void
output(integer a, integer b, text condition)
{
o_integer(a);
o_text(condition);
o_integer(b);
o_byte('\n');
}

integer
main(void)
{
if (a < b) {
output(a, b, " is less then ");
}

if (a == b) {
output(a, b, " is equal to ");
}

if (a > b) {
output(a, b, " is greater than ");
}

return 0;
}```

Run as:

`aime FILE integer a 33 integer b 133`

## ALGOL 68

Works with: ALGOL 68 version Revision 1 - no extensions to language used
Works with: ALGOL 68G version Any - tested with release 1.18.0-9h.tiny
Works with: ELLA ALGOL 68 version Any (with appropriate job cards) - tested with release 1.8-8d

Note: the standard includes the characters "≤", "≥" and "≠". These appear in the character sets GOST 10859, ISOtech and IBM's EBCDIC e.g. code page 293, and in extended ASCII code pages 910 & 910

The above distributions of both ALGOL 68G and ELLA ALGOL 68 compilers only allow ASCII characters (ASCII has neither "≤", "≥" nor "≠" characters).

```main: (
INT a, b;

IF a <= b OR a LE b # OR a ≤ b # THEN
print((a," is less or equal to ", b, new line))
FI;
IF a < b OR a LT b THEN
print((a," is less than ", b, new line))
ELIF a = b OR a EQ b THEN
print((a," is equal to ", b, new line))
ELIF a > b OR a GT b THEN
print((a," is greater than ", b, new line))
FI;
IF a /= b OR a NE b # OR a ≠ b # THEN
print((a," is not equal to ", b, new line))
FI;
IF a >= b OR a GE b # OR a ≥ b # THEN
print((a," is greater or equal to ", b, new line))
FI
)```
Output:
```+3 is less or equal to          +4
+3 is less than          +4
+3 is not equal to          +4
```

## ALGOL W

```begin

integer a, b;

write( "first  number: " );
write( "second number: " );

if a < b then write( a, " is less    than ", b );
if a = b then write( a, " is equal   to   ", b );
if a > b then write( a, " is greater than ", b );

end.```

## AppleScript

```set n1 to text returned of (display dialog "Enter the first number:" default answer "") as integer
set n2 to text returned of (display dialog "Enter the second number:" default answer "") as integer
set msg to {n1}
if n1 < n2 then
set end of msg to " is less than "
else if n1 = n2 then
set end of msg to " is equal to "
else if n1 > n2 then
set end of msg to " is greater than "
end if
set end of msg to n2
return msg as string
```

Or...

```set n1 to text returned of (display dialog "Enter the first number:" default answer "") as integer
set n2 to text returned of (display dialog "Enter the second number:" default answer "") as integer
if n1 < n2 then return "" & n1 & " is less than " & n2
if n1 = n2 then return "" & n1 & " is equal to " & n2
if n1 > n2 then return "" & n1 & " is greater than " & n2
```

## AutoHotkey

Error checking is performed automatically by attaching UpDowns to each of the Edit controls. UpDown controls always yield an in-range number, even when the user has typed something non-numeric or out-of-range in the Edit control. The default range is 0 to 100.

```Gui, Add, Edit

## Avail

```// This code doesn't try to protect against any malformed input.
a ::= next line from standard input→integer;

## AWK

```/[0-9]* [0-9]*/{
if (\$1 == \$2) print \$1, "is equal to", \$2
if (\$1 < \$2) print \$1, "is less than", \$2
if (\$1 > \$2) print \$1, "is greater than", \$2
}
```

In awk, a double equals symbol is required to test for equality. A single equals sign is used for assignment, and will cause a bug if it is used within a boolean expression:

```# This code contains a bug
IF (n=3) PRINT "n is equal to 3"    # The incorrectly used equals sign will set n to a value of 3
```

### FutureBasic

Note: Strictly speaking, it's preferable to use "==" when comparing integers as seen in this example. While the "=" sign will work as a comparison in most cases, technically it should be used for assignment, i.e. a = 3 when a is assigned the value of 3, as contrasted with a == 3, where the value of a is being compared with 3. FB will flag a warning when "==" is used to compare two single, doubles or floats since comparing real numbers can be inaccurate.

if (a > b) print "a is greater than b\n"
if (a == b) print "a is equal to b\n"
quit

## Clojure

Creates an infinite sequence of calls to "read an object from the user", and assigns the first two elements to a and b, without evaluating the rest. It evaluates the when/println body three times, each time with op and string bound to their corresponding entries in the list of three operator/string pairs. Note that this does no validation on input: if the user inputs a string then an exception will be thrown.

```(let [[a b] (repeatedly read)]
(doseq [[op string] [[< "less than"]
[> "greater than"]
[= "equal to"]]]
(when (op a b)
(println (str a " is " string " " b)))))
```

## CMake

```# Define A and B as integers. For example:
#   cmake -DA=3 -DB=5 -P compare.cmake

# The comparisons can take variable names, or they can take numbers.
# So these act all the same:
#   A LESS B
#   \${A} LESS \${B}
#   A LESS \${B}
#   \${A} LESS B

if(A LESS B)
message(STATUS "\${A} is less than \${B}")
endif()
if(A EQUAL B)
message(STATUS "\${A} is equal to \${B}")
endif()
if(A GREATER B)

## Common Lisp

You can type this directly into a REPL:

```(let ((a (read *standard-input*))
(cond
((not (numberp a)) (format t "~A is not a number." a))
((not (numberp b)) (format t "~A is not a number." b))
((< a b) (format t "~A is less than ~A." a b))
((> a b) (format t "~A is greater than ~A." a b))
((= a b) (format t "~A is equal to ~A." a b))
(t (format t "Cannot determine relevance between ~A and ~B!" a b)))))
```

After hitting enter, the REPL is expecting the two numbers right away. You can enter the two numbers, and the result will print immediately. Alternatively, you can wrap this code in a function definition:

```(defun compare-integers ()
(cond
((not (numberp a)) (format t "~A is not a number." a))
((not (numberp b)) (format t "~A is not a number." b))
((< a b) (format t "~A is less than ~A." a b))
((> a b) (format t "~A is greater than ~A." a b))
((= a b) (format t "~A is equal to ~A." a b))
(t (format t "Cannot determine relevance between ~A and ~B!" a b)))))
```

Then, execute the function for better control:

```(compare-integers)
```

## Computer/zero Assembly

The only conditional instruction we have is BRZ (branch on accumulator zero). We can therefore test for equality very quickly. To test for "greater than" or "less than", however, requires a loop.

If you run this program, it will halt awaiting user input. Toggle in the value of ${\displaystyle x}$, then click Enter, then toggle in ${\displaystyle y}$, then Enter, and then Run. ${\displaystyle x}$ and ${\displaystyle y}$ must both be unsigned eight-bit integers. The computer will halt with the accumulator storing 1 if ${\displaystyle x}$>${\displaystyle y}$, 0 if ${\displaystyle x}$=${\displaystyle y}$, or -1 if ${\displaystyle x}$<${\displaystyle y}$; and it will be ready for a fresh pair of integers to be entered.

```start:  STP        ; get input

x:      NOP
y:      NOP

LDA  x
SUB  y
BRZ  start ; x=y, A=0

loop:   LDA  x
SUB  one
BRZ  x<y
STA  x

LDA  y
SUB  one
BRZ  x>y
STA  y

JMP  loop

x>y:    LDA  one   ; A := 1
JMP  start

x<y:    SUB  one   ; A := 0-1
JMP  start

one:         1```

if (a == b)

Output:

## EDSAC order code

The EDSAC offers two conditional branching orders, E (branch if the accumulator >= 0) and G (branch if the accumulator < 0). Testing for equality thus requires two operations.

## Efene

since if does pattern matching the else is required to avoid the application from crashing

}

if A < B {
io.format("~p is less than ~p~n", [A, B])

## Emacs Lisp

```(defun integer-comparison (a b)
"Compare A to B and print the outcome in the message buffer."

`=IF(\$A1>\$B1;concatenate(\$A1;" is greater than ";\$B1);IF(\$A1<\$B1;concatenate(\$A1;" is smaller than ";\$B1);concatenate(\$A1;" is equal to ";\$B1)))`

`=IF(\$A1>\$B1,concatenate(\$A1," is greater than ",\$B1),IF(\$A1<\$B1,concatenate(\$A1," is smaller than ",\$B1),concatenate(\$A1," is equal to ",\$B1)))`

## F#

## Fermat

```Func Compare =
?a;
?b;
if a=b then !'Equal' fi;
if a<b then !'Less than' fi;
if a>b then !'Greater than' fi;

## Fish

This example assumes you pre-populate the stack with the two integers.

```l2=?vv ~<                                                        v o<
v   <>l?^"Please pre-populate the stack with the two integers."ar>l?^;
\\$:@@:@)?v   v               ;oanv!!!?<
>\$n" is greater than "{r>ol1=^
/            <
\\$:@@:@=?v   v           ;oanv!!!?<
>\$n" is equal to "{r>ol1=^
/            <
\\$:@@:@(?v   v               ;oanv!!!?<
>\$n" is smaller than "{r>ol1=^
>        v
/oo". "nooooo" and "n\$<                                                            v o<
>"They're not equal, not greater than and not smaller than eachother... strange."ar>l?^;
```

The last three lines aren't really needed, because it will never become true :P but I included them to show a way to do some error checking.

## Forth

To keep the example simple, the word takes the two numbers from the stack.

```: compare-integers ( a b -- )
2dup < if ." a is less than b" then
2dup > if ." a is greater than b" then
= if ." a is equal to b" then ;
```

## Fortran

In ALL Fortran versions (including original 1950's era) you could use an "arithmetic IF" statement to compare using subtraction:

```program arithif
integer a, b

c        fortran 77 I/O statements, for simplicity

if ( a - b ) 10, 20, 30
10 write(*,*) a, ' is less than ', b
goto 40

20 write(*,*) a, ' is equal to ', b
goto 40

30 write(*,*) a, ' is greater than ', b
40 continue

end
```

In ANSI FORTRAN 66 or later you could use relational operators (.lt., .gt., .eq., etc.) and unstructured IF statements:

```program compare
integer a, b
c        fortran 77 I/O statements, for simplicity

if (a .lt. b) write(*, *) a, ' is less than ', b
if (a .eq. b) write(*, *) a, ' is equal to ', b
if (a .gt. b) write(*, *) a, ' is greater than ', b
end
```

In ANSI FORTRAN 77 or later you can use relational operators and structured IF statements:

```program compare
integer a, b

if (a .lt. b) then
write(*, *) a, ' is less than ', b
else if (a .eq. b) then
write(*, *) a, ' is equal to ', b
else if (a .gt. b) then
write(*, *) a, ' is greater than ', b
end if

end
```

In ISO Fortran 90 or later you can use symbolic relational operators (<, >, ==, etc.)

```program compare
integer :: a, b

if (a < b) then
write(*, *) a, ' is less than ', b
else if (a == b) then
write(*, *) a, ' is equal to ', b
else if (a > b) then
write(*, *) a, ' is greater than ', b
end if

end program compare
```

## friendly interactive shell

```read a

if test \$a -gt \$b
echo Greater
else if test \$a -lt \$b
echo Less
else if test \$a -eq \$b
echo Equal
end
```

## Frink

All integers in Frink can be arbitrarily large.

```[a,b] = eval[input["Enter numbers",["a","b"]]]
if a<b
println["\$a < \$b"]
if a==b
println["\$a == \$b"]
if a>b
println["\$a > \$b"]```

## FunL

```import console.readInt

val (_, c) = [((<), 'less than'), ((==), 'equal to'), ((>), 'greater than')].find( (compare, _) -> compare(a, b) ).get()

println( "\$a is \$c \$b." )```

## Fōrmulæ

Fōrmulæ programs are not textual, visualization/edition of programs is done showing/manipulating structures but not text. Moreover, there can be multiple visual representations of the same program. Even though it is possible to have textual representation —i.e. XML, JSON— they are intended for storage and transfer purposes more than visualization and edition.

Programs in Fōrmulæ are created/edited online in its website.

In this page you can see and run the program(s) related to this task and their results. You can also change either the programs or the parameters they are called with, for experimentation, but remember that these programs were created with the main purpose of showing a clear solution of the task, and they generally lack any kind of validation.

Solution

Fōrmulæ has an intrinsic expression for three-way comparison that works for integers and other types (decimal and rational numbers, strings, time expressions, etc). It returns expressions that flag one of the three possible results.

However, a simple function can be written for the requirement:

## Go

```package main

import (
"fmt"
"log"
)

func main() {
var n1, n2 int
fmt.Print("enter number: ")
if _, err := fmt.Scan(&n1); err != nil {
log.Fatal(err)
}
fmt.Print("enter number: ")
if _, err := fmt.Scan(&n2); err != nil {
log.Fatal(err)
}
switch {
case n1 < n2:
fmt.Println(n1, "less than", n2)
case n1 == n2:
fmt.Println(n1, "equal to", n2)
case n1 > n2:
fmt.Println(n1, "greater than", n2)
}
}
```

## Groovy

### Relational Operators

```def comparison = { a, b ->
println "a ? b    = \${a} ? \${b}    = a \${a < b ? '<' : a > b ? '>' : a == b ? '==' : '?'} b"
}
```

Program:

```comparison(2000,3)
comparison(2000,300000)
comparison(2000,2000)
```
Output:
```a ? b    = 2000 ? 3    = a > b
a ? b    = 2000 ? 300000    = a < b
a ? b    = 2000 ? 2000    = a == b```

### "Spaceship" (compareTo) Operator

Using spaceship operator and a lookup table:

```final rels = [ (-1) : '<', 0 : '==', 1 : '>' ].asImmutable()
def comparisonSpaceship = { a, b ->
println "a ? b    = \${a} ? \${b}    = a \${rels[a <=> b]} b"
}
```

Program:

```comparison(2000,3)
comparison(2000,300000)
comparison(2000,2000)
```
Output:
```a ? b    = 2000 ? 3    = a > b
a ? b    = 2000 ? 300000    = a < b
a ? b    = 2000 ? 2000    = a == b```

## Harbour

```PROCEDURE Compare( a, b )

IF a < b
? "A is less than B"
ELSEIF a > b
? "A is more than B"
ELSE
? "A equals B"
ENDIF

RETURN
```

```myCompare :: Integer -> Integer -> String
myCompare a b
| a < b  = "A is less than B"
| a > b  = "A is greater than B"
| a == b = "A equals B"

main = do
putStrLn \$ myCompare a b
```

However, the more idiomatic and less error-prone way to do it in Haskell would be to use a compare function that returns type Ordering, which is either LT, GT, or EQ:

```myCompare a b = case compare a b of
LT -> "A is less than B"
GT -> "A is greater than B"
EQ -> "A equals B"
```

## hexiscript

```let a scan int
let b scan int

if a < b
println a + " is less than " + b
endif

if a > b
println a + " is greater than " + b
endif

if a = b
println a + " is equal to " + b
endif```

end
}```

## Icon and Unicon

```procedure main()

until integer(a) do {
writes("Enter the first integer a := ")
}

until integer(b) do {
writes("Enter the second integer b := ")
}
writes("Then ")
write(a," < ", a < b)
write(a," = ", a = b)
write(a," > ", a > b)
end
```
Output:
```#int_compare.exe
Enter the first integer a := 7
Enter the second integer b := 7
Then 7 = 7```

## J

Comparison is accomplished by the verb `compare`, which provides logical-numeric output.
Text elaborating the output of `compare` is provided by `cti`:

```compare=: < , = , >

select  =. ;@#
English =. ' is less than ';' is equal to ';' is greater than '
x (":@[, (compare select English"_), ":@]) y
)
```

Examples of use:

```   4 compare 4
0 1 0
4 cti 3
4 is greater than 3
```

## Java

```import java.io.*;

public class compInt {
public static void main(String[] args) {
try {

if(nbr1<nbr2)
System.out.println(nbr1 + " is less than " + nbr2);

if(nbr1>nbr2)
System.out.println(nbr1 + " is greater than " + nbr2);

if(nbr1==nbr2)
System.out.println(nbr1 + " is equal to " + nbr2);
} catch(IOException e) { }
}
}
```

## JavaScript

```// Using type coercion
function compare(a, b) {
if (a==b) print(a + " equals " + b);
if (a < b) print(a + " is less than " + b);
if (a > b) print(a + " is greater than " + b);
}

// Without using type coercion and using standards
// Written for browsers
// assumption of a and b are both integers if typeof test passes
function compare (a, b) {
if (typeof a === typeof b) {
if (a === b) {
document.writeln(a + " equals " + b);
}
if (a < b) {
document.writeln(a + " is less than " + b);
}
if (a > b) {
document.writeln(a + " is greater than " + b);
}
} else {
// "1" and 1 are an example of this as the first is type string and the second is type number
print(a + "{" + (typeof a) + "} and " + b + "{" + (typeof b) + "} are not of the same type and cannot be compared.");
}

## Lingo

Lingo programs are normally not run in the console, so interactive user input is handled via GUI. To not clutter this page with GUI creation code, here only the comparison part of the task:

```on compare (a, b)
if a < b then put a&" is less than "&b
if a = b then put a&" is equal to "&b
if a > b then put a&" is greater than "&b
end```

## LiveCode

```ask question "Enter 2 numbers (comma separated)" with empty titled "Enter 2 numbers"
if it is not empty then
put item 1 of it into num1
put item 2 of it into num2
if isnumber(num1) and isnumber(num2) then
if num1 < num2 then answer num1 && "is less than" && num2
if num1 is num2 then answer num1 && "is equal to" && num2
if num1 > num2 then answer num1 && "is greater than" && num2

-- alternative is to use switch case construct
switch

answer num1 && "is less! than" && num2; break
case (num1 > num2)
answer num1 && "is greater! than" && num2; break

```to compare :a :b
if :a = :b [(print :a [equals] :b)]
if :a < :b [(print :a [is less than] :b)]
if :a > :b [(print :a [is greater than] :b)]
end```

Each infix operator has prefix synonyms (equalp, equal?, lessp, less?, greaterp, greater?), where the 'p' stands for "predicate" as in Lisp.

## Lua

```print('Enter the first number: ')
print('Enter the second number: ')

if a < b then print(a .. " is less than " .. b) end
if a > b then print(a .. " is greater than " .. b) end
if a == b then print(a .. " is equal to " .. b) end
```

In lua, a double equals symbol is required to test for equality. A single equals sign is used for assignment, and will cause an error during jit precompilation, if it is used within a boolean expression:

```-- if a = b then print("This will not work")
```

## Maple

```CompareNumbers := proc( )
local a, b;
printf( "Enter a number:> " );
printf( "Enter another number:> " );
if a < b then

elif a = b then
printf("The first number is equal to the second");
elif a > b then
printf("The first number is greater than the second");
end if;
end proc:

CompareNumbers();```

## Mathematica / Wolfram Language

```a=Input["Give me the value for a please!"];
b=Input["Give me the value for b please!"];
If[a==b,Print["a equals b"]]
If[a>b,Print["a is bigger than b"]]

```

## Maxima

```/* all 6 comparison operators (last is "not equal") */

## ML/I

This reads the two numbers from 'standard input' or similar, and outputs the results to 'standard output' or equivalent. Note that ML/I only has tests for equality, greater-than, and greater-than-or-equal.

## Perl

Works with: Perl version 5.x

Separate tests for less than, greater than, and equals

```sub test_num {
my \$f = shift;
my \$s = shift;
if (\$f < \$s){
return -1; # returns -1 if \$f is less than \$s
} elsif (\$f > \$s) {
return 1; # returns 1 if \$f is greater than \$s
} elsif (\$f == \$s) {
# = operator is an assignment
# == operator is a numeric comparison
return 0; # returns 0 \$f is equal to \$s
};
};```

All three tests in one. If \$f is less than \$s return -1, greater than return 1, equal to return 0

```sub test_num {
return \$_[0] <=> \$_[1];
};```

Note: In Perl, \$a and \$b are (kind of) reserved identifiers for the built-in sort function. It's good style to use more meaningful names, anyway.

```# Get input, test and display
print "Enter two integers: ";
(\$x, \$y) = split ' ', <>;
print \$x, (" is less than ", " is equal to ",
" is greater than ")[test_num(\$x, \$y) + 1], \$y, "\n";```

## Phix

puts(1,"equal to")
elsif a > b then
puts(1,"greater than")
end if

## PHP

```<?php

echo "Enter an integer [int1]: ";
fscanf(STDIN, "%d\n", \$int1);
if(!is_numeric(\$int1)) {
echo "Invalid input; terminating.\n";
exit(1);      // return w/ general error
}

echo "Enter an integer [int2]: ";
fscanf(STDIN, "%d\n", \$int2);
if(!is_numeric(\$int2)) {
echo "Invalid input; terminating.\n";
exit(1);      // return w/ general error
}

// now \$int1 and \$int2 are numbers.
// for simplicity, this does not explicitly examine types

if(\$int1 < \$int2)
echo "int1 < int2\n";
if(\$int1 == \$int2)
echo "int1 = int2\n";
if(\$int1 > \$int2)
echo "int1 > int2\n";

?>```

Note that this works from the command-line interface only, whereas PHP is usually executed as wp:Common_Gateway_Interface CGI.

## Python

b = input('Enter value of b: ')

if a < b:
print 'a is less than b'
elif a > b:
print 'a is greater than b'
elif a == b:
print 'a is equal to b'```

(Note: in Python3 input() will become int(input()))

An alternative implementation could use a Python dictionary to house a small dispatch table to be indexed by the results of the built-in cmp() function. cmp() returns a value suitable for use as a comparison function in a sorting algorithm: -1, 0 or 1 for <, = or > respectively. Thus we could use:

Works with: Python version 2.x only, not 3.x
```#!/usr/bin/env python
import sys
try:
a = input('Enter value of a: ')
b = input('Enter value of b: ')
except (ValueError, EnvironmentError), err:
print sys.stderr, "Erroneous input:", err
sys.exit(1)

dispatch = {
-1: 'is less than',
0: 'is equal to',
1: 'is greater than'
}
print a, dispatch[cmp(a,b)], b```

In this case the use of a dispatch table is silly. However, more generally in Python the use of dispatch dictionaries or tables is often preferable to long chains of elif' clauses in a condition statement. Python's support of classes and functions (including currying, partial function support, and lambda expressions) as first class objects obviates the need for a "case" or "switch" statement.

## Raku

(formerly Perl 6)

```my \$a = prompt("1st int: ").floor;
my \$b = prompt("2nd int: ").floor;

if \$a < \$b {
say 'Less';
}
elsif \$a > \$b {
say 'Greater';
}
elsif \$a == \$b {
say 'Equal';
}```

With `<=>`:

`say <Less Equal Greater>[(\$a <=> \$b) + 1];`

A three-way comparison such as <=> actually returns an `Order` enum which stringifies into 'Decrease', 'Increase' or 'Same'. So if it's ok to use this particular vocabulary, you could say that this task is actually a built in:

`say prompt("1st int: ") <=> prompt("2nd int: ");`

if a > b
' a is bigger than b
else
if b > a
' b is bigger than a
else
' a is equal to b
end if

## RPG

Two integers are passed as parameters. Because the command line casts numeric literals as packed(15,5), calling from the command line requires the user to specify the 8 nybbles in hexadecimal form:

CALL rc_intcmp (x'00000000' x'00000001')

```     h dftactgrp(*no)

d                 pi
d integer1                      10i 0
d integer2                      10i 0

d message         s             50a

if integer1 < integer2;
message = 'Integer 1 is less than integer 2';
endif;

if integer1 > integer2;

## Ruby

This uses Kernel#gets to get input from STDIN, and String#to_i to convert the string into an integer. (Without this conversion, Ruby would compare strings: 5 < 10 but "5" > "10".)

```a = (print "enter a value for a: "; gets).to_i
b = (print "enter a value for b: "; gets).to_i

puts "#{a} is less than #{b}" if a < b
puts "#{a} is greater than #{b}" if a > b
puts "#{a} is equal to #{b}" if a == b```

Another way:

```a = (print "enter a value for a: "; gets).to_i
b = (print "enter a value for b: "; gets).to_i

case a <=> b
when -1; puts "#{a} is less than #{b}"
when  0; puts "#{a} is equal to #{b}"
when +1; puts "#{a} is greater than #{b}"
end```

Example input and output:

``` \$ '''ruby compare.rb'''
enter a value for a: '''5'''
enter a value for b: '''10'''
5 is less than 10
\$ '''ruby compare.rb'''
enter a value for a: '''cat'''
enter a value for b: '''dog'''
0 is equal to 0
```

Translation of: Python

An alternative method, which is similar to the python version mentioned above (at the time of writing this) is:

```# Function to make prompts nice and simple to abuse
def prompt str
print str, ": "
gets.chomp
end

# Get value of a
a = prompt('Enter value of a').to_i
# Get value of b
b = prompt('Enter value of b').to_i

# The dispatch hash uses the <=> operator
# When doing x<=>y:
# -1 means x is less than y
# 0 means x is equal to y
# 1 means x is greater than y
dispatch = {
-1 => "less than",
0 => "equal to",
1 => "greater than"
}

# I hope you can figure this out
puts "#{a} is #{dispatch[a<=>b]} #{b}"```

## Rust

Reading from stdin into a string is cumbersome at the moment, but convenience functions will be implemented in the future.

## SNOBOL4

Comparisons in Snobol are not operators, but predicate functions that return a null string and generate a success or failure value which allows or blocks statement execution, and which can be tested for branching. Other numeric comparisons are ge (>=), le (<=) and ne (!= ). There is also a parallel set of L-prefixed predicates in modern Snobols for lexical string comparison.

```*       # Get user input
output = 'Enter X,Y:'
trim(input) break(',') . x ',' rem . y

output = lt(x,y) x ' is less than ' y :s(end)
output = eq(x,y) x ' is equal to '  y :s(end)
output = gt(x,y) x ' is greater than ' y
end```

## SNUSP

There are no built-in comparison operators, but you can (destructively) check which of two adjacent cells is most positive.

```++++>++++ a b !/?\<?\#  a=b
> -  \#  a>b
- <
a<b #\?/```

## Sparkling

## SSEM

The SSEM only provides one conditional operation: 011 Test, which causes execution to skip one instruction if the value in the accumulator is negative. We can use this to implement conditional tests along the lines of the following pseudocode:

```            accumulator := a - b;
if accumulator >= 0 then
(* a is not less than b, so *)
goto next_test
else
goto less;
next_test:  accumulator := accumulator - 1;
if accumulator >= 0 then
goto greater
else
(* a and b are equal *)
accumulator := 0;
halt;
greater:    accumulator := 1;
halt;
less:       accumulator := -1;
halt```

To run the SSEM program, load A into storage address 21 and B into storage address 22. No additional space is used. Like the pseudocode version, the program halts with the accumulator holding 1 if A>B, 0 if A=B, or -1 if A<B.

## Standard ML

```fun compare_integers(a, b) =
if a < b then print "A is less than B\n"
if a > b then print "A is greater than B\n"
if a = b then print "A equals B\n"

fun test () =
let
open TextIO
val SOME a = Int.fromString (input stdIn)
val SOME b = Int.fromString (input stdIn)
in
compare_integers (a, b)
end
handle Bind => print "Invalid number entered!\n"```

A more idiomatic and less error-prone way to do it in SML would be to use a compare function that returns type order, which is either LESS, GREATER, or EQUAL:

```fun myCompare (a, b) = case Int.compare (a, b) of
LESS    => "A is less than B"
| GREATER => "A is greater than B"
| EQUAL   => "A equals B"```

## Swift

```import Cocoa

var input = NSFileHandle.fileHandleWithStandardInput()

println("Enter two integers separated by a space: ")

let data = input.availableData
let stringArray = NSString(data: data, encoding: NSUTF8StringEncoding)?.componentsSeparatedByString(" ")
var a:Int!
var b:Int!
if (stringArray?.count == 2) {
a = stringArray![0].integerValue
b = stringArray![1].integerValue
}
if (a==b)  {println("\(a) equals \(b)")}
if (a < b) {println("\(a) is less than \(b)")}
if (a > b) {println("\(a) is greater than \(b)")}```
Output:
```Enter two integers separated by a space:
234 233
234 is greater than 233```

## Tcl

This is not how one would write this in Tcl, but for the sake of clarity:

```puts "Please enter two numbers:"

gets stdin x
gets stdin y

if { \$x > \$y } { puts "\$x is greater than \$y" }
if { \$x < \$y } { puts "\$x is less than \$y" }
if { \$x == \$y } { puts "\$x equals \$y" }```

Other comparison operators are "<=", ">=" and "!=".

Note that Tcl doesn't really have a notion of a variable "type" - all variables are just strings of bytes and notions like "integer" only ever enter at interpretation time. Thus the above code will work correctly for "5" and "6", but "5" and "5.5" will also be compared correctly. It will not be an error to enter "hello" for one of the numbers ("hello" is greater than any integer). If this is a problem, the type can be expressly cast

`if {int(\$x) > int(\$y)} { puts "\$x is greater than \$y" }`

or otherwise type can be checked with "if { string is integer \$x }..."

Note that there is no substitution/evaluation here anywhere: entering "3*5" and "15" will parse "3*5" as a non-numerical string (like "hello") and thus the result will be "3*5 is greater than 15".

A variant that iterates over comparison operators, demonstrated in an interactive tclsh:

```% set i 5;set j 6
% foreach {o s} {< "less than" > "greater than" == equal} {if [list \$i \$o \$j] {puts "\$i is \$s \$j"}}
5 is less than 6
% set j 5
% foreach {o s} {< "less than" > "greater than" == equal} {if [list \$i \$o \$j] {puts "\$i is \$s \$j"}}
5 is equal 5
% set j 4
% foreach {o s} {< "less than" > "greater than" == equal} {if [list \$i \$o \$j] {puts "\$i is \$s \$j"}}
5 is greater than 4```

## Toka

```[ ( a b -- )
2dup < [ ." a is less than b\n" ] ifTrue
2dup > [ ." a is greater than b\n" ] ifTrue
= [ ." a is equal to b\n" ] ifTrue
] is compare-integers

1 1 compare-integers
2 1 compare-integers
1 2 compare-integers```

## TUSCRIPT

```\$\$ MODE TUSCRIPT

IF (i1!='digits'||i2!='digits') ERROR/STOP "Please insert digits"

IF (i1==i2) PRINT i1," is equal to     ",i2
IF (i1<i2)  PRINT i1," is less than    ",i2
IF (i1>i2)  PRINT i1," is greater than ",i2```

## UNIX Shell

There are multiple examples here, because each shell has a different form of the 'read' command.

Works with: ksh93
```#!/bin/ksh
# tested with ksh93s+

builtin printf

integer a=0
integer b=0

read a?"Enter value of a: " || { print -u2 "Input of a aborted." ; exit 1 ; }
read b?"Enter value of b: " || { print -u2 "Input of b aborted." ; exit 1 ; }

if (( a < b )) ; then
printf "%d is less than %d\n" a b
fi
if (( a == b )) ; then
printf "%d is equal to %d\n" a b
fi
if (( a > b )) ; then
printf "%d is greater than %d\n" a b
fi

exit 0```

One can backport the previous code to pdksh, which has no builtin printf, but can call /usr/bin/printf as an external program.

Works with: pdksh
```#!/bin/ksh
# tested with pdksh

integer a=0
integer b=0

read a?"Enter value of a: " || { print -u2 "Input of a aborted." ; exit 1 ; }
read b?"Enter value of b: " || { print -u2 "Input of b aborted." ; exit 1 ; }

if (( a < b )) ; then
printf "%d is less than %d\n" \$a \$b
fi
if (( a == b )) ; then
printf "%d is equal to %d\n" \$a \$b
fi
if (( a > b )) ; then
printf "%d is greater than %d\n" \$a \$b
fi

exit 0```

Works with: Bash
```read -p "Enter two integers: " a b

if [ \$a -gt \$b ]; then comparison="greater than"
elif [ \$a -lt \$b ]; then comparison="less than"
elif [ \$a -eq \$b ]; then comparison="equal to"
else comparison="not comparable to"
fi

echo "\${a} is \${comparison} \${b}"```

## Ursa

```decl int first second
out "enter first integer:  " console
set first (in int console)
out "enter second integer: " console
set second (in int console)

if (= first second)
out "the two integers are equal" endl console
end if
if (< first second)
out first " is less than " second endl console
end if
if (> first second)
out first " is greater than " second endl console
end if```

## V

```[compare
[ [>] ['less than' puts]
[<] ['greater than' puts]
[=] ['is equal' puts]
] when].

|2 3 compare
greater than
|3 2 compare
less than
|2 2 compare
is equal```

## Vala

```void main(){
int	a;
int	b;

if (a < b)
stdout.printf("%d is less than %d\n", a, b);
if (a == b)
stdout.printf("%d is equal to %d\n", a,	b);
if (a > b)
stdout.printf("%d is greater than %d\n", a, b);
}```

## Wart

```a <- (read)
prn (if (a < b)
: "a is less than b"
(a > b)
: "a is greater than b"
:else
: "a equals b")```

## Wren

```import "io" for Stdin, Stdout

System.print("Enter anything other than a number to quit at any time.\n")
while (true) {
System.write("  First number  : ")
Stdout.flush()
if (!a) break
System.write("  Second number : ")
Stdout.flush()
if (!b) break
var s = (a-b).sign
if (s < 0) {
System.print("  %(a) < %(b)")
} else if (s == 0) {
System.print("  %(a) == %(b)")
} else {
System.print("  %(a) > %(b)")
}
System.print()
}```
Output:

Sample session:

```Enter anything other than a number to quit at any time.

First number  : 5
Second number : 23
5 < 23

First number  : 56
Second number : 6
56 > 6

First number  : 4
Second number : 4
4 == 4

First number  : q
```

## XLISP

```(DEFUN COMPARE-INTEGERS ()
(DISPLAY "Enter two integers separated by a space.")
(NEWLINE)
(DISPLAY "> ")
(COND
((> A B) (DISPLAY "The first number is larger."))
((= A B) (DISPLAY "They are equal."))
((< A B) (DISPLAY "The first number is smaller."))))```

## XPL0

```code IntIn=10, Text=12;
int A, B;
[A:= IntIn(0);
B:= IntIn(0);
if A<B then Text(0, "A<B");
if A=B then Text(0, "A=B");
if A>B then Text(0, "A>B");
CrLf(0);
]```

## XSLT

Because XSLT uses XML syntax, the less than and greater than operators which would normally be written '<' and '>' must be escaped using character entities, even inside of XPath expressions.

```<xsl:template name="compare">
<xsl:param name="a" select="1"/>
<xsl:param name="b" select="2"/>
<fo:block>
<xsl:choose>
<xsl:when test="\$a &lt; \$b">a &lt; b</xsl:when>
<xsl:when test="\$a &gt; \$b">a &gt; b</xsl:when>
<xsl:when test="\$a = \$b">a = b</xsl:when>
</xsl:choose>
</fo:block>
</xsl:template>```

## zkl

```var x,y; x,y=ask("Two ints: ").split(" ").apply("toInt")
(if (x==y) "equal" else if (x<y) "less" else if(x>y) "greater").println()```
Output:
```Two ints: 3 2
greater
```
