Ordinal Numbers

This week we're going to write a function to turn a cardinal integer into an ordinal number (eg. 4 becomes 4th). This is mostly useful when generating a page to display to a visitor.

ASP

1. function ordinal(ByVal cardinal)
2.     cardinal = CStr(cardinal)
4.     if Right(cardinal, 1) = "1" and Right(cardinal, 2) <> "11" then
5.         ordinal = cardinal & "st"
6.     elseif Right(cardinal, 1) = "2" and Right(cardinal, 2) <> "12" then
7.         ordinal = cardinal & "nd"
8.     elseif Right(cardinal, 1) = "3" and Right(cardinal, 2) <> "13" then
9.         ordinal = cardinal & "rd"
10.     else
11.         ordinal = cardinal & "th"
12.     end if
13. end function

PHP

1. function ordinal($cardinal)
2. {
3.     if (substr($cardinal, -1, 1) == 1 && substr($cardinal, -2, 2) != 11)
4.     {
5.         return ($cardinal . 'st');
6.     }
7.     elseif (substr($cardinal, -1, 1) == 2 && substr($cardinal, -2, 2) != 12)
8.     {
9.         return ($cardinal . 'nd');
10.     }
11.     elseif (substr($cardinal, -1, 1) == 3 && substr($cardinal, -2, 2) != 13)
12.     {
13.         return ($cardinal . 'rd');
14.     }
15.     else
16.     {
17.         return ($cardinal . 'th');
18.     }
19. }
