prng.onchain.js

A micro JS implementation (112 bytes) of the Mulberry32 pseudorandom number generator.

This library is intended for use in environments where the available storage space is very limited; like blockchains for example. Everything is stripped down to the bare essentials.

Usage

// Initialize a random generator for a given seed value
let rand = Pr.ng(1234)
rand()
// => 0.07329497812315822
rand()
// => 0.7034119898453355
rand()
// => 0.9028560190927237

// Re-initialize to start the same sequence again using the same seed value
rand = Pr.ng(1234)
rand()
// => 0.07329497812315822
rand()
// => 0.7034119898453355
rand()
// => 0.9028560190927237
