NAME

Math::Random::ISAAC::PP - Pure Perl port of the ISAAC PRNG Algorithm

VERSION

Version 1.001 ($Id: PP.pm 8611 2009-08-18 00:19:18Z FREQUENCY@cpan.org $)

SYNOPSIS

This module implements the same interface as Math::Random::ISAAC and can be used as a drop-in replacement. However, it is recommended that you let the Math::Random::ISAAC module decide whether to use the PurePerl or XS version of this module, instead of choosing manually.

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

DESCRIPTION

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