Lingua::EN::FindNumber - Locate (written) numbers in English text

  use Lingua::EN::FindNumber;
  my $text = "Fourscore and seven years ago, our four fathers...";

  numify($text); # "87 years ago, our 4 fathers..."

  @numbers = extract_numbers($text); # "Fourscore and seven", "four"

  while ($text =~ /$number_re/g) { # Build your own iterator

This module provides a regular expression for finding numbers in English text. It also provides functions for extracting and manipulating such numbers.

  numify($text); # "87 years ago, our 4 fathers..."

  @numbers = extract_numbers($text); # "Fourscore and seven", "four"

  while ($text =~ /$number_re/g) { # Build your own iterator

This module was written for the Natural Languages chapter of the second edition of Advanced Perl Programming. If you liked the module, why not buy the book?

This module works rather well in conjunction with Lingua::EN::Words2Nums, which is a very cool module anyway. (And I stole some of this module's code from it. Thanks, Joey!) It may also be involved with Lingua::EN::NamedEntity in the future, so check that one out too.
