NAME

Shannon::Entropy::XS - Calculate the Shannon entropy H of a given input string faster.

VERSION

Version 1.11

SYNOPSIS

Calculate the Shannon entropy H of a given input string.

       use Shannon::Entropy::XS qw/entropy/;

       entropy('1223334444'); # 1.8464393446710154
       entropy('0123456789abcdef'); # 4

entropy

BENCHMARK

use Benchmark qw(:all);
use Shannon::Entropy;
use Shannon::Entropy::XS;

timethese(10000000, {
	'Entropy' => sub {
		my $string = 'thisusedtobeanemail@gmail.com';
		Shannon::Entropy::entropy($string);
	},
	'XS' => sub {
		my $string = 'thisusedtobeanemail@gmail.com';
		Shannon::Entropy::XS::entropy($string);
	}
});
