NAME
Parse::Number::EN - Parse number from English text
VERSION
This document describes version 0.07 of Parse::Number::EN (from Perl distribution Parse-Number-EN), released on 2016-06-14.
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).
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.
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.
This function is not exported by default, but exportable.
Arguments ('*' denotes required arguments):
text* => str
The input text that contains number.
Return value: (any)
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.
