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.
