## Installation

    $ npm install mersenne-twister

## Usage

```javascript
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:

```javascript
var generator = new MersenneTwister(123);
``` 

and that will always produce the same random sequence.

Also you can do it on existing generator instance:

```javascript
generator.init_seed(123);
```
