Pseudorandom number generator 
Mersenne Twister pseudorandom number generator.
Origin source (generator interface was changed)
Algorithm - http://en.wikipedia.org/wiki/Mersenne_twister
Installation
$ npm install mersenne-twister
Usage
var MersenneTwister = require('mersenne-twister');
var generator = new MersenneTwister();
// Generates a random number on [0,1) real interval (same interval as Math.random)
generator.random();
// [0, 4294967295]
generator.random_int();
// [0,1]
generator.random_incl();
// (0,1)
generator.random_excl();
// [0,1) with 53-bit resolution
generator.random_long();
// [0, 2147483647]
generator.random_int31();Seeding
If you want to use a specific seed in order to get a repeatable random sequence, pass an integer into the constructor:
var generator = new MersenneTwister(123);and that will always produce the same random sequence.
Also you can do it on existing generator instance:
generator.init_seed(123);License
