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

SYNOPSIS
    use Math::Random::MT;

    $gen = Math::Random::MT->new($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 and seeds it appropriately.

    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.
