NAME

       Lingua::EN::Number::IsOrdinal - detect if English number is ordinal or cardinal

SYNOPSIS

           use Lingua::EN::Number::IsOrdinal 'is_ordinal';

           ok is_ordinal('first');

           ok !is_ordinal('one');

           ok is_ordinal('2nd');

           ok !is_ordinal('2');

DESCRIPTION

       This module will tell you if a number, either in words or as digits, is a cardinal or
       ordinal number <http://www.ego4u.com/en/cram-up/vocabulary/numbers/ordinal>.

       This is useful if you e.g. want to distinguish these types of numbers found with
       Lingua::EN::FindNumber and take different actions.

FUNCTIONS

   is_ordinal
       Takes a number as English words or digits (with or without ordinal suffix) and returns 1
       for ordinal numbers and "undef" for cardinal numbers.

       Checks that the whole parameter is a number using Lingua::EN::FindNumber or a regex in the
       case of digits, and if it isn't will throw a "not a number" exception.

       This function can be optionally imported.

METHODS

   _is_ordinal
       Method version of "is_ordinal", this is where the function is actually implemented. Can be
       overloaded in a subclass.

   _is_number
       Returns 1 if the passed in string is a word-number as detected by Lingua::EN::FindNumber
       or is a cardinal or ordinal number made of digits and (for ordinal numbers) a suffix.
       Otherwise returns "undef". Can be overloaded in a subclass.
