Parse::Number::EN - Parse number from English text
This document describes version 0.06 of Parse::Number::EN (from Perl distribution Parse-Number-EN), released on 2015-09-03.
use Parse::Number::EN qw(parse_number_en $Pat); my @a = map {parse_number_en(text=>$_)} ("12,345.67", "-1.2e3", "x123", "1.23", "1,23"); # @a = (12345.67, -1200, undef, 1.23, 1) my @b = map {/^$Pat$/ ? 1:0} ("12,345.67", "-1.2e3", "x123", "1,23"); # @b = (1, 1, 0, 0)
The goal for this module is to parse/extract numbers written in some common notation in English text. That means, in addition to what Perl does, it also recognizes thousand separators (and fractions, percentages in the future).
Parse number from English text.
This function can parse number with thousand separators (e.g. 10,000).
In the future percentage (e.g. 10.2%) and fractions (e.g. 1/3, 2 1/2) might also be supported.
Arguments ('*' denotes required arguments):
text* => str
The input text that contains number.
Return value: (any)
None are exported by default, but they are exportable.
A regex for quickly matching/extracting number from text. It's not 100% perfect (the extracted number might not be valid), but it's simple and fast.
This module uses a single regex and provides the regex for you to use. Other modules might be more accurate and/or faster. But this module is pretty fast.
