For general numbers there is Lingua::EN::FindNumber. Here's an example from its POD:

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"

It's pretty easy to use, and surprisingly thorough, though I haven't had a chance to test if it handles fractions.
