rand0m

Deterministic pseudo-random value generator in JavaScript.

• Implements a Lehmer random number generator.
• Simple implementation in pure JavaScript, without any dependencies.
• Compatible with Browsers, Node.js, React Native, etc.

This is NOT a cryptographically secure random number generator. The intention is to generate a sequence of random numbers that can be re-generated when using the same seed.

Install

$ npm install rand0m

How to use it

const Rand0m = require('rand0m');

const seed = 1337; // Some seed, must be an integer!
const randomGenerator = new Rand0m(seed);

randomGenerator.int(); // Returns an integer between 0 and 4294967295.
randomGenerator.float(); // Returns a float between 0 and 1.
randomGenerator.int(1, 10); // Returns an integer between 1 and 10.
randomGenerator.float(10.5, 19.2); // Returns an float between 10.5 and 19.2.
