ordinate(SCALAR) 
Returns a string consisting of that scalar’s string form, plus the
appropriate ordinal suffix. Example: ordinate(23) returns 23rd.
As a special case, ordinate(undef) and ordinate("") return 0th, not th. This function is exported by default. 
th(SCALAR)  Merely an alias for ordinate, but not exported by default. 
ordsuf(SCALAR) 
Returns just the appropriate ordinal suffix for the given scalar
numeric value. This is what ordinate uses to actually do its
work. For example, ordsuf(3) is rd.
Not exported by default. 
* Note that this library knows only about numbers, not numberwords. ordinate(seven) might just as well be ordinate(superglue) or ordinate("\x1E\x9A") — you’ll get the fallthru case of the input string plus th.* As is unavoidable, ordinate(0256) returns 174th (because ordinate sees the value 174). Similarly, ordinate(1E12) returns 1000000000000th. Returning trillionth would be nice, but that’s an awfully atypical case.
* Note that this library’s algorithm (as well as the basic concept and implementation of ordinal numbers) is totally language specific.
To pick a trivial example, consider that in French, 1 ordinates as 1ier, whereas 41 ordinates as 41ieme.
Bored of this...?
use Lingua::EN::Numbers::Ordinate qw(ordinate th); ... print th($n), " entry processed...\n"; ...Try this bit of lunacy:
{ my $th_object; sub _th () { $th_object } package Lingua::EN::Numbers::Ordinate::Overloader; my $x; # Gotta have something to bless. $th_object = bless \$x; # Define the object now, which _th returns use Carp (); use Lingua::EN::Numbers::Ordinate (); sub overordinate { Carp::croak "_th should be used only as postfix!" unless $_[2]; Lingua::EN::Numbers::Ordinate::ordinate($_[1]); } use overload & => \&overordinate; }Then you get to do:
print 3 & _th, "\n"; # prints "3rd" print 1 + 2 & _th, "\n"; # prints "3rd" too! # Because of the precedence of & ! print _th & 3, "\n"; # dies with: "th should be used only as postfix!"Kooky, isn’t it? For more delightful deleria like this, see Damian Conway’s Object Oriented Perl from Manning Press.
Kinda makes you like th(3), doesn’t it?
Lingua::EN::Inflect provides an ORD function, which returns the ordinal form of a cardinal number.Lingua::EN::Number::IsOrdinal provides an is_ordinal function, which returns true if passed an ordinal number.
