TT800(3pm)

NAME

Math::Random::TT800 - Matsumoto's TT800 Pseudorandom number generator

DESCRIPTION

This perl extension module implements M. Matsumoto's twisted
generalized shift register generator called TT800 as described in his
article published in ACM Transactions on Modelling and Computer
Simulation, Vol. 4, No. 3, 1994, pages 254-266.

SYNOPSIS

use Math::Random::TT800;

my $tt = new Math::Random::TT800;

$value = $tt->next();

$ivalue = $tt->next_int();

FUNCTIONS

new: my $tt = new Math::Random::TT800;
my $tt = new Math::Random::TT800 @seeds;
Create a new TT800 object. Providing seeds is optional. A TT800 takes 25 integers as seed which must not be all zero. If less than 25 integers are supplied, the rest are taken from the default seed.
next: $value = $tt->next();
next returns the next pseudorandom number from the TT800 object as a floating point value in the range [0,1).
next_int: $ivalue = $tt->next_int();
next_int returns a integer value filled with 32 random bits.
