Lingua::EN::Numericalize - Replaces English descriptions of numbers with numerals
use Lingua::EN::Numericalize; print str2nbr("one thousand maniacs"); $_ = "six hundred three-score and six"; str2nbr(); print; $Lingua::EN::Numericalize::UK = 1; print str2nbr("one billion"); # 1,000,000,000,000
This module interpolates English descriptions of numbers in a given string with their numeric counterparts. It supports both ordinal and cardinal numbers, negative numbers, and very large numbers.
The module exports a single function into the caller's namespace as follows:
This function receives an optional string (using $_ if none is passed) and converts all English text that describes a number into its numeric equivalent. When called in a void context, the function sets $_ to the new value.
The module's behaviour is affected by the following variables:
This variable may be set to indicate that the UK meaning of
billion should be used. By default, this module uses the American meaning of this word :( Please note that all the related larger numbers e.g. trillion, quadrillion, etc. assume the chosen behaviour as well.
If set to true, the module outputs on standard error messages useful for debugging.
Scores are supported, e.g. "three score and six", so are dozens, baker's dozens and grosses.
Cardinal numbers become ordinal i.e. second => 2, 13th => 13.
Various mispellings are understood, as are plurals, "illions" (e.g. million, billion, etc.), and "illiards" (e.g. milliard, billiard, etc.) in addition to suffixes e.g. 1k => 1000, 2M, 3B. Extended hundreds are also supported e.g. twelve hundred = one thousand two hundred = 1200.
While it handles googol correctly, googolplex is too large to fit in perl's standard scalar type, and "inf" will be returned.

This module was inspired by Joey Hess' Words2Nums but is a complete rewrite with an entirely different internal approach. It differs from his module in that it is smart enough to ignore strings it doesn't recognise, thus preempting the impossible requirement that the user first parse the string. As an example, a string like
One Thousand Maniacs would fail if passed to Words2Nums (since it contains
Maniacs) and doing a split and passing each individual piece would yield
1 1000 maniacs instead of the desired
