NAME
    Math::Random::MT - The Mersenne Twister PRNG

SYNOPSIS
     use Math::Random::MT;

     $gen = Math::Random::MT->new($seed); # OR...
     $gen = Math::Random::MT->new(@seed);

     print $gen->rand(3);

     OR

     use Math::Random::MT qw(srand rand);

     # now srand and rand behave as usual.

DESCRIPTION
    The Mersenne Twister is a pseudorandom number generator developed by
    Makoto Matsumoto and Takuji Nishimura. It is described in their paper at
    <URL:http://www.math.keio.ac.jp/~nisimura/random/doc/mt.ps>.

    This module implements two interfaces, as described in the synopsis
    above. It defines the following functions.

  Functions
    new($seed)
        Creates a new generator seeded with an unsigned 32-bit integer.

    new(@seed)
        Creates a new generator seeded with an array of (up to 624) unsigned
        32-bit integers.

    rand($num)
        Behaves exactly like Perl's builtin rand(), returning a number
        uniformly distributed in [0, $num) ($num defaults to 1).

    srand($seed)
        This is an alternative interface to the module's functionality. It
        behaves just like Perl's builtin srand(). If you use this interface,
        it is strongly recommended that you call *srand()* explicitly,
        rather than relying on *rand()* to call it the first time it is
        used.
