NAME
Parse::Number::EN - Pattern to match number
VERSION
This document describes version 0.05 of Parse::Number::EN (from Perl
distribution Parse-Number-EN), released on 2014-10-03.
SYNOPSIS
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)
DESCRIPTION
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).
FUNCTIONS
parse_number_en(%args) -> any
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)
VARIABLES
None are exported by default, but they are exportable.
$Pat (REGEX)
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.
FAQ
How does this module differ from other number-parsing modules?
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.
