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.
