You are encouraged to solve this task according to the task description, using any language you may know.
Programming languages often have built-in routines to convert a non-negative integer for printing in different number bases. Such common number bases might include binary, Octal and Hexadecimal.
Show how to print a small range of integers in some different bases, as supported by standard routines of your programming language. (Note: this is distinct from Number base conversion as a user-defined conversion function is not asked for.)
The reverse operation is Common number base parsing.

AWK
C's printf() is just exposed: <lang awk>$ awk '{printf("%d 0%o 0x%x\n",$1,$1,$1)}' 10 10 012 0xa 16 16 020 0x10 255 255 0377 0xff</lang>
C
<lang c>#include <stdio.h>
int main() {
int i;
for(i=1; i <= 33; i++) printf("%6d %6x %6o\n", i, i, i);
return 0;
}</lang>
Binary conversion using %b is not standard.
C++
<lang cpp>#include <iostream>
- include <iomanip>
int main() {
for (int i = 0; i <= 33; i++) std::cout << std::setw(6) << std::dec << i << " " << std::setw(6) << std::hex << i << " " << std::setw(6) << std::oct << i << std::endl;
return 0;
}</lang>
Binary conversion is not standard.
Clojure
Clojure eschews duplicating functionality already present in Java when interop is sufficiently idiomatic: <lang lisp>(Integer/toBinaryString 25) ; returns "11001" (Integer/toOctalString 25) ; returns "31" (Integer/toHexString 25) ; returns "19"
(dotimes [i 20]
(println (Integer/toHexString i)))</lang>
Common Lisp
<lang lisp>(loop for n from 0 to 33 do
(format t " ~6B ~3O ~2D ~2X~%" n n n n))</lang>
D
<lang d>import std.stdio;
void main() {
writeln("Base: 2 8 10 16"); writeln("----------------------------"); foreach (i; 0 .. 34) writefln(" %6b %6o %6d %6x", i, i, i, i);
}</lang>

Forth
GNU Forth has convenience functions for printing an integer in decimal or hex, regardless of the current BASE. <lang forth>: main 34 1 do cr i dec. i hex. loop ; main ... 11 $B ...</lang> This is not standardized because such functions are very easy to define as needed: <lang forth>: base. ( n base -- ) base @ >r base ! . r> base ! ;
- oct. ( n -- ) 8 base. ;
- bin. ( n -- ) 2 base. ;</lang>
Fortran
<lang fortran>do n = 1, 33
write(*, "(b6, o4, i4, z4)") n, n, n, n
end do</lang>
Gema
After decimal numbers in the input stream, add hexadecimal and octal of the same number in the output stream. Also after hexadecimal add decimal and octal, and after octal add decimal and hexadecimal. <lang gema>0x<A>=$0 (@radix{16;10;$1}, 0@radix{16;8;$1}) 0<D>=$0 (@radix{8;10;$1}, 0x@radix{8;16;$1}) <D>=$0 (0x@radix{10;16;$1}, 0@radix{10;8;$1})</lang> Invocation and sample input and output

Go
<lang go>package main
import (
"fmt" "math/big" "strconv"
)
func main() {
// package strconv: // Itoa is the most common int to string conversion. it is base 10 only. x := strconv.Itoa(13) fmt.Printf("%q\n", x)
// FormatInt handles arbitrary bases from 2 to 36. x = strconv.FormatInt(1313, 19) fmt.Printf("%q\n", x)
// package fmt: allows direct conversion from integer // to string types for bases 2, 8, 10, and 16. fmt.Printf("%b\n", 13) fmt.Printf("%o\n", 13) fmt.Printf("%d\n", 13) fmt.Printf("%x\n", 13)

Icon and Unicon
Strictly speaking output conversion to different representations isn't built-in to Icon and Unicon; however, printf is included as part of the standard library. <lang Icon>rocedure main() write("Non-decimal radices/Output") every i := 255 | 2 | 5 | 16 do {
printf("%%d = %d\n",i) # integer format printf("%%x = %x\n",i) # hex format printf("%%o = %o\n",i) # octal format printf("%%s = %s\n",i) # string format printf("%%i = %i\n",i) # image format }
end</lang>
printf.icn provides printf, fprintf, and sprintf
Output:
%d = 255 %x = ff %o = 377 %s = 255 %i = 255 ...
J
J can natively break out numbers using a specific base
<lang j> 2 #.inv 12 1 1 0 0
3 #.inv 100
1 0 2 0 1
16 #.inv 180097588
10 11 12 1 2 3 4</lang> However, this numeric representation would not satisfy most people's idea of "formatting", for most bases. It might be useful, however, for bases less than 10:
<lang j> 8 #.inv 4009 7 6 5 1
-.&' '": 8 #.inv 4009
7651</lang> J also includes some explicit support for hexadecimal numbers
<lang j> require 'convert'
hfd 180097588
ABC1234</lang> (and a few other hexadecimal related mechanisms which are not relevant here.)
Java
<lang java5>public static void main(String args[]){
for(int a= 0;a < 33;a++){ System.out.println(Integer.toBinaryString(a)); System.out.println(Integer.toOctalString(a)); System.out.println(Integer.toHexString(a)); //the above methods treat the integer as unsigned //there are also corresponding Long.to***String() methods for long's.
System.out.printf("%3o %2d %2x\n",a ,a ,a); //printf like the other languages; binary not supported }
}</lang>
JavaScript
The number.toString(radix)
method produces a string representation of a number in any radix between 2 and 36.
<lang javascript>var bases = [2, 8, 10, 16, 24]; for (var n = 0; n <= 33; n++) {
var row = []; for (var i = 0; i < bases.length; i++) row.push( n.toString(bases[i]) ); print(row.join(', '));

print " {0:6b} {1:3o} {2:2d} {3:2X}".format(n, n, n, n) #The following would give the same output, and, #due to the outer brackets, works with Python 3.0 too #print ( " {n:6b} {n:3o} {n:2d} {n:2X}".format(n=n) )

Octal (o), Decimal (d), and Hexadecimal (X and x), but not binary are supported by the string modulo operator, %: <lang python>for n in range(34): print " %3o %2d %2X" % (n, n, n)</lang>
For each of these bases there is also a built-in function that will convert it to a string with the proper prefix appended, so that it is a valid Python expression: <lang python>n = 33
- Python 3.x:
print(bin(n), oct(n), n, hex(n)) # bin() only available in Python 3.x and 2.6
- output: 0b100001 0o41 33 0x21
- Python 2.x:
- print oct(n), n, hex(n)
- output: 041 33 0x21</lang>
R
Conversion to and from binary does not have built-in support. <lang R># dec to oct as.octmode(x)
- dec to hex
as.hexmode(x)
- oct or hex to dec
as.integer(x)
- or
as.numeric(x)</lang>
REXX
version 1
Note that some REXX interpreters have the D2B (decimal-->binary) built-in function.
So, the D2B function was coded here for those REXX interpreters that don't have that function.
<lang rexx>/*REXX program shows REXX's ability to show decimal numbers in bin & hex*/
do j=0 to 50 /*show some low-value num conversions*/ say right(j,3) ' in decimal is', right(d2b(j),12) " in binary", right(d2x(j),12) ' in hexadecimal.' end /*j*/
exit /*stick a fork in it, we're done.*/
/*────────────────────────────D2B subroutine────────────────────────────*/ d2b: procedure; _=x2b(d2x(arg(1))) /*with this function, dec──>bin is OK*/
/*Note: some newer REXX interpreters */ /* have the D2B func built-in.*/ if _=0 then return 0 /*handle special case of 0000 (zero).*/ return strip(_,'L',0) /*return answer with no leading 0's. */</lang>

version 2
Rexx also has the ability to use base 256 and uses the D2C and C2D function for this purpose.
Of course, using base 256 is hampered in ASCII machines in that some lower values are
interpreted by the operating system as control characters and therefore aren't displayed as their (true) glyph.
<lang rexx>
/*REXX program shows REXX's ability to show dec nums in bin/hex/base256.*/
do j=14 to 67 /*display some lower-value numbers. */ say right(j,3) ' in decimal is', right(d2b(j),12) " in binary", right(d2x(j),12) ' in hexadecimal', right(d2c(j),12) ' in base256.' end
exit
/*────────────────────────────D2B subroutine────────────────────────────*/ d2b: procedure; _=x2b(d2x(arg(1))) /*with this function, dec-->bin is OK*/
if _=0 then return 0 /*handle special case of 0000 (zero).*/ return strip(_,'L',0) /*return answer with no leading 0's. */

Scheme
<lang scheme>(do ((i 0 (+ i 1)))
((>= i 33)) (display (number->string i 2)) ; binary (display " ") (display (number->string i 8)) ; octal (display " ") (display (number->string i 10)) ; decimal, the "10" is optional (display " ") (display (number->string i 16)) ; hex (newline))</lang>
Smalltalk
The radix can be from 2 to 49 and its value is prepended to the string followed by "r". <lang smalltalk>1 to: 33 do: [ :i |

Seed7
The function str converts an integer number to a string. The conversion uses the numeral system with the given base. The base can be any integer value between 2 and 36. <lang seed7>$ include "seed7_05.s7i";
const proc: main is func
local var integer: i is 0; begin for i range 1 to 33 do writeln(i lpad 6 <& str(i, 8) lpad 6 <& str(i, 16) lpad 6); end for; end func;</lang>

Tcl
The format
command supports conversions to octal, decimal, and hex:
<lang tcl>for {set n 0} {$n <= 33} {incr n} {
puts [format " %3o %2d %2X" $n $n $n]
}</lang>
TI-89 BASIC
Bases 2, 10, and 16 are supported. The base is controlled by a global mode.
<lang ti89b>Local old getMode("Base")→old setMode("Base", "BIN") Disp string(16) setMode("Base", "HEX") Disp string(16) setMode("Base", "DEC") Disp string(16) setMode("Base", old)</lang>
