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 . 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.
