21 This module will tell you if a number, either in words or as digits, is
22 a cardinal or ordinal number <http://www.ego4u.com/en/cram-
23 up/vocabulary/numbers/ordinal>.
24
25 This is useful if you e.g. want to distinguish these types of numbers
26 found with Lingua::EN::FindNumber and take different actions.

29 is_ordinal
30 Takes a number as English words or digits (with or without ordinal
31 suffix) and returns 1 for ordinal numbers and "undef" for cardinal
32 numbers.
33
34 Checks that the whole parameter is a number using
35 Lingua::EN::FindNumber or a regex in the case of digits, and if it
36 isn't will throw a "not a number" exception.
37
38 This function can be optionally imported.
