mtprng

Mersenne twister MT19937 pseudorandom number generator for Haxe language, tested on Haxe 3.3

based on http://www.math.sci.hiroshima-u.ac.jp/~m-mat/MT/emt.html and https://gist.github.com/banksean/300494

Install using haxelib

haxelib install mtprng

Creating new MT instance

var mt = new mtprng.MT( 42 ); // 42 is the PRNG seed
var mt = new mtprng.MT();			// use default seed (haxe.Timer.stamp())

Methods

• randomUInt() -- returns pseudorandom UInt in range [0,2^32)
• randomInt() -- returns pseudorandom Int in range [-2^31,2^31)
• randomFloat() -- returns pseudorandom Float with 53-bits precision
• randomFloat32() -- returns pseudorandom Float with 32-bits precision

Make from array key

• MT.makeFromArray( initKey: Array<UInt> )

Using static instance

var x = mtprng.MT.instance.randomInt();
var y = mtprng.MT.instance.randomFloat();

Platforms

• cpp, cs, java, js, neko, swf: works, passes all tests
• lua, python: works somehow, passes half of the tests
• php: fails all tests
