SYNOPSIS

9         use Lingua::EN::Numbers qw(num2en num2en_ordinal);
10
11         my $x = 234;
12         my $y = 54;
13         print "You have ", num2en($x), " things to do today!\n";
14         print "You will stop caring after the ", num2en_ordinal($y), ".\n";
15
16       prints:
17
18         You have two hundred and thirty-four things to do today!
19         You will stop caring after the fifty-fourth.

DESCRIPTION

22       This module provides a function "num2en", which converts a number (such
23       as 123) into English text ("one hundred and twenty-three").  It also
24       provides a function "num2en_ordinal", which converts a number into the
25       ordinal form in words, so 54 becomes "fifty-fourth".
26
27       If you pass either function something that doesn't look like a number,
28       they will return "undef".
29
30       This module can handle integers like "12" or "-3" and real numbers like
31       "53.19".
32
33       This module also understands exponential notation -- it turns "4E9"
34       into "four times ten to the ninth").  And it even turns "INF", "-INF",
35       "NaN" into "infinity", "negative infinity", and "not a number",
36       respectively.
37
38       Any commas in the input numbers are ignored.

LEGACY INTERFACE

41       The first version of this module, 0.01 released in May 1995, had an OO
42       interface. This was finally dropped in the 1.08 release.

46       modules for converting numbers into English words.
47
48       The following modules will convert a number into words:
49
50       ·   Lingua::EN::Inflect provides a lot more besides, including
51           conversion of singular to plural, selecting whether to use 'an' or
52           'a' before a word, and plenty more
53
54       ·   Lingua::EN::Nums2Words provides similar functionality, but can't
55           handle exponential notation, and 3.14 produces "three and fourteen
56           hundredths" instead of "three point one four".
57
58       ·   Math::BigInt::Named doesn't work.
59
60       ·   Number::Spell doesn't handle negative numbers, exponential
61           notation, or non-integer real numbers. The generated text doesn't
62           contain any commas or the word 'and', so the results for long
63           numbers don't scan.
64
65       There are other modules which provide related, but not identical,
66       functionality:
67
68       ·   Lingua::EN::Numbers::Ordinate provides a function that will convert
69           a cardinal number (such as "3") to an ordinal ("3rd").
70
71       ·   Lingua::EN::Numbers::Years provides a function that will convert a
72           year in numerals (eg "1984") into words ("nineteen eighty-four").
73
74       ·   Lingua::EN::Fractions provides a function that will convert a
75           numeric fraction (eg "3/4") into words ("three quarters").
