I'm not sure if the post was just showing off HOP::Parser or what but I hacked together the following code just based on intuition. hehe. Tried to figure out exactly how i processed the numbers and make the computer do that.

use strict; use warnings; use Data::Dumper; use Test::More qw/no_plan/; my $nums_to_value = {}; my $i = 0; for (qw/zero one two three four five six seven eight nine ten eleven twelve thirteen fourteen fifteen sixteen seventeen eigh +tteen nineteen/) { $nums_to_value->{$_} = $i++; }; $i = 20; for (qw/twenty thirty forty fifty sixty seventy eighty ninety/) { $nums_to_value->{$_} = $i; $i += 10; } my $mag = { hundred => 100, thousand => 1_000, million => 1_000_000, billion => 1_000_000_000, }; #print Dumper($nums_to_value); sub num { my $word = shift; if (index( $word, '-') > 0) { my ($first,$second) = split /-/, $_; return undef unless exists $nums_to_value->{$first} and exists $nums_to_value->{$second}; return $nums_to_value->{$first} + $nums_to_value->{$second}; } else { return undef unless exists $nums_to_value->{$word}; return $nums_to_value->{$word}; } } sub word_to_decimal { my @words = @_; my $out; my $i = 0; for (@words) { my $temp = num($_); $i += length($temp); $out += $temp / 10**$i; } return $out; } sub word_to_num { my $text = shift; my @words = split / /, $text; my @que; my $scratch = 0; my $mod = 1; if ($words[0] eq 'negative') { $mod = -1; shift @words; } while (@words) { $_ = shift @words; my $temp = num($_); if (defined $temp) { $scratch += $temp; } elsif($_ eq 'and') { } elsif($_ eq 'point') { push @que, word_to_decimal(@words); @words = (); } else { my $magnitude = $mag->{$_}; my $sum = $scratch; while (@que && ($sum + $que[-1]) < $magnitude) { $sum += pop @que; } my $temp = ($sum || 1) * $magnitude; push @que, $temp; $scratch = 0; } } push @que, $scratch; my $out = sum(@que); return $mod * $out; } sub sum { my $temp = 0; $temp += $_ for @_; return $temp; } my $words = { 'three' => 3, 'forty' => 40, 'hundred' => 100, 'fourteen' => 14, 'thousand' => 1000, 'forty-two' => 42, 'ninety nine' => 99, 'hundred and two' => 102, 'hundred nineteen' => 119, 'hundred and twenty' => 120, 'hundred ninety-nine' => 199, 'two hundred and three' => 203, 'one thousand two hundred' => 1_200, 'one point one zero zero one' => 1.1001, 'negative hundred and three' => -103, 'twelve hundred and seventy three', => 1273, 'seven hundred thirty-three thousand' => 733_000, 'seven hundred thirty-three thousand five hundred', 733500, 'seven hundred thirty-three thousand five hundred and twenty-nine' +, 733529, 'seventy three point two four five' => 73.245, 'three point seventeen' => 3.17, 'seven million' => 7000000, 'two hundred and ninety six million four hundred and twenty-two th +ousand five hundred and seventy eight', 296_422_578, 'two hundred and ninety six million four hundred and twenty-two th +ousand five hundred and seventy eight point three four seven', 296422578.347, }; for my $word (sort {length $a <=> length $b} keys %$words) { my $num = $words->{$word}; is word_to_num($word), $num, "... $word should be $num"; }

It passes all your tests, but i'm not sure that means it will pass everything. Anyway just felt like hacking it together. ;)

Update: Turns out there IS a module for this. Still fun anyway and we have three completly different methods. Lingua::EN::Words2Nums
