NAME
Math::RNG::Microsoft::FCPro - a pseudo-random number generator compatible with Visual C with Freecell Pro extended seeds.
VERSION
version 0.4.0
SYNOPSIS
use Math::RNG::Microsoft::FCPro ();
my $randomizer = Math::RNG::Microsoft::FCPro->new(seed => 24);
my $random_digit = $randomizer->rand_max(10);DESCRIPTION
This is a random number generator used by Freecell::Deal::MS which emulates the one found in Microsoft's Visual C++. It was utilised here, out of familiarity and accessibility, because it is commonly used to generate Freecell layouts in the Freecell world (see http://en.wikipedia.org/wiki/FreeCell_%28Windows%29 ).
NOTE: This is not a cryptologically secure random number generator, nor is it a particularly good one, so its use is discouraged unless compatibility with the Windows C Run-time-library is needed.
SUBROUTINES/METHODS
new
The constructor. Accepts a numeric seed as an argument.
my $randomizer = Math::RNG::Microsoft::FCPro->new(seed => 1);$randomizer->rand()
Returns a random integer from 0 up to 0x7fff - 1.
my $n = $randomizer->rand()$randomizer->max_rand($max)
Returns a random integer in the range 0 to ($max-1).
my $n = $randomizer->max_rand($max);
# $n is now between 0 and $max - 1.my $array_ref = $randomizer->shuffle(\@array)
Shuffles the array reference of the first argument, destroys it and returns it. This is using the fisher-yates shuffle.
my $new_array_ref = $randomizer->fresh_shuffle(\@array)
Copies the array reference of the first argument to a new array, shuffles it and returns it. This is using the fisher-yates shuffle.
@array remains unchanged.
(Added in version 0.4.0 .)
