rkgttr-prng

Small and fast pseudo random number generator. Not the most complex or bullet-proof of PRNGs out there, but fast and small when you want to have "predictable" random numbers. I don't know the period of this generator: I've run a script that generates a million numbers per second and after a day and a half (188 billions iterations) the sequence still did not repeat. So I guess it's good enough.

How to Install

$ npm install rkgttr-prng --save-dev

or

$ yarn add rkgttr-prng --dev

Getting Started

var Prng = require('rkgttr-prng');
 
var prng = new Prng();
prng.gen();

or

import Prng from 'rkgttr-prng';
 
let prng = new Prng();
prng.gen();

When creating a PRNG instance, you can pass a seed to it:

let prng = new Prng(12);
