Math::Random::ISAAC::XS(3) C implementation of the ISAAC PRNG algorithm


version 1.004


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();


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