A simple, no-frills, seedable random number generator from sha256 hashes.
Written in plain JavaScript. Depends on Node.js Crypto.
Installation
npm install seedableUsage
const createRng = require("seedable");
const rng = createRng(); // same as createRng(0)
rng.value; // -> 0.7383370615243194
rng.float(); // -> 0.9614931357219447 (same as rng.value)
rng.int(); // -> 100808138967781
rng.int(0, 10); // -> 4
rng.int() / rng.maxInt; // -> 0.103077615824823 (same as rng.value)
Array.from({ length: 5 }, rng.float);
