NAME

6       Lingua::EN::Words2Nums - convert English text to numbers
7

SYNOPSIS

9        use Lingua::EN::Words2Nums;
10        $num=words2nums("two thousand and one");
11        $num=words2nums("twenty-second");
12        $num=words2nums("15 billion, 6 million, and ninteen");

DESCRIPTION

15       This module converts English text into numbers. It supports both
16       ordinal and cardinal numbers, negative numbers, and very large numbers.
17
18       The main subroutine, which is exported by default, is words2nums().
19       This subroutine, when fed a string, will attempt to convert it into a
20       number.  If it succeeds, the number will be returned. If it fails, it
21       returns undef.
22

VARIABLES

24       There are a number of variables that can be used to tweak the behavior
25       of this module. For example, debugging can be be enabled by setting
26       $Lingua::EN::Words2Nums::debug=1
27
28       $Lingua::EN::Words2Nums::debug
29           Default: 0. If set to a true value, outputs on standard error some
30           useful messages if parsing fails for some reason.
31
32       $Lingua::EN::Words2Nums::billion
33           Default: 10 ** 9. This is the number that will be returned for "one
34           billion".  It defaults to the American version; the English will
35           want to set it to 10 ** 12. Setting this number automatically
36           changes all the larger numbers (trillion, quadrillion, etc) to
37           match.

NOTES

40       It does not understand decimals or fractions, yet.
41
42       Scores are supported, eg: "four score and ten". So are dozens. So is a
43       baker's dozen. And a gross.
44
45       Various mispellings of numbers are understood.
46
47       While it handles googol correctly, googolplex is too large to fit in
48       perl's standard scalar type, and "inf" will be returned.
