=head1 NAME
Math::Random::TT800 - Matsumoto's TT800 Pseudorandom number generator
=head1 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.
=head1 SYNOPSIS
use Math::Random::TT800;
my $tt = new Math::Random::TT800;
$value = $tt->next();
$ivalue = $tt->next_int();
=head1 FUNCTIONS
=over 4
=item 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.
=item next
$value = $tt->next();
next returns the next pseudorandom number from the TT800 object as
a floating point value in the range [0,1).
=item next_int
$ivalue = $tt->next_int();
next_int returns a integer value filled with 32 random bits.
