# N'th

**N'th**

You are encouraged to solve this task according to the task description, using any language you may know.

Write a function/method/subroutine/... that when given an integer greater than or equal to zero returns a string of the number followed by an apostrophe then the ordinal suffix.

Example returns would include `1'st 2'nd 3'rd 11'th 111'th 1001'st 1012'th`

- Task

Use your routine to show here the output for *at least* the following (inclusive) ranges of integer inputs:
`0..25, 250..265, 1000..1025`

**Note:** apostrophes are now *optional* to allow correct apostrophe-less English.

## COBOL[edit]

COBOL stores numbers in decimal form, so there is no need to use a modulo function: the last digit or the last two digits can be extracted directly.

IDENTIFICATION DIVISION.

PROGRAM-ID. NTH-PROGRAM.

DATA DIVISION.

WORKING-STORAGE SECTION.

01 WS-NUMBER.

05 N PIC 9(8).

05 LAST-TWO-DIGITS PIC 99.

05 LAST-DIGIT PIC 9.

05 N-TO-OUTPUT PIC Z(7)9.

05 SUFFIX PIC AA.

PROCEDURE DIVISION.

TEST-PARAGRAPH.

PERFORM NTH-PARAGRAPH VARYING N FROM 0 BY 1 UNTIL N IS GREATER THAN 25.

PERFORM NTH-PARAGRAPH VARYING N FROM 250 BY 1 UNTIL N IS GREATER THAN 265.

PERFORM NTH-PARAGRAPH VARYING N FROM 1000 BY 1 UNTIL N IS GREATER THAN 1025.

STOP RUN.

NTH-PARAGRAPH.

MOVE 'TH' TO SUFFIX.

MOVE N (7:2) TO LAST-TWO-DIGITS.

IF LAST-TWO-DIGITS IS LESS THAN 4,

OR LAST-TWO-DIGITS IS GREATER THAN 20,

THEN PERFORM DECISION-PARAGRAPH.

MOVE N TO N-TO-OUTPUT.

DISPLAY N-TO-OUTPUT WITH NO ADVANCING.

DISPLAY SUFFIX WITH NO ADVANCING.

DISPLAY SPACE WITH NO ADVANCING.

DECISION-PARAGRAPH.

MOVE N (8:1) TO LAST-DIGIT.

IF LAST-DIGIT IS EQUAL TO 1 THEN MOVE 'ST' TO SUFFIX.

IF LAST-DIGIT IS EQUAL TO 2 THEN MOVE 'ND' TO SUFFIX.

IF LAST-DIGIT IS EQUAL TO 3 THEN MOVE 'RD' TO SUFFIX.

Output:

A more concise, albeit less readable version:

This version adds suffixes without apostrophes.

Negative numbers and fractions are also handled.

th: parse arg z; x=abs(z); return z||word('th st nd rd',1+x//10*(x//100%10\==1)*(x//10<4))

## Sinclair ZX81 BASIC[edit]

Works flawlessly with 2k or more of RAM. With 1k, the subroutine itself works but you can't quite print all the tests: the program crashes with an 'out of memory' error code after 1017th. (A slightly less useful and readable version gets as far as 1023rd; 1025th is probably attainable, but might involve obfuscating the program more than is appropriate for this site.)
