NAME

Math::Random::ISAAC::XS - C implementation of the ISAAC PRNG Algorithm

VERSION

Version 1.0.1 ($Id: XS.pm 6046 2009-04-07 07:08:50Z FREQUENCY@cpan.org $)

SYNOPSIS

This module implements the same interface as Math::Random::ISAAC and can be used as a drop-in replacement. This is the recommended implementation of the module, based on Bob Jenkins' reference implementation in C.

Selecting the backend to use manually really only has two uses:

  • If you are trying to avoid the small overhead incurred with dispatching method calls to the appropriate backend modules.

  • If you are testing the module for performance and wish to explicitly decide which module you would like to use.

Example code:

# With Math::Random::ISAAC
my $rng = Math::Random::ISAAC->new(time);
my $rand = $rng->rand();

# With Math::Random::ISAAC::XS
my $rng = Math::Random::ISAAC::XS->new(time);
my $rand = $rng->rand();

DESCRIPTION

See Math::Random::ISAAC for the full description.

$rng->rand()
