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. SEE ALSO * Lingua::EN::FindNumber * Lingua::EN::Words2Nums * Lingua::EN::Inflect::Phrase AUTHOR Rafael Kitover
