Squares: A Fast Counter-Based RNG (Random Number Generator)
- Original author (of paper and original C code) → Bernard Widynski (email@example.com)
- arXiv paper (May 5, 2020)
- Website with original C code
- Predictive (pure function) → For any integer, n, squares(n) will always produce the same 'random' number.
- Counter-based (think mappable, stateless) → Each next random number is not based on a previous one;
rather, a random number is simply a function of the non-negative integers
(ℕ₀ ≡ (0, 1, 2, 3, ... )), i.e.
- Crush-proof → Passes statistical BigCrush tests
- Synchronous WASM → no
asyncrequired! (due to the WASM Module being read from a static Base64 string and not from a file or url)
Basically any browser supporting WebAssembly - most major browsers since October 2017.
- No → IE 11
- Yes → Chrome 57+, Edge 16+, Firefox 53+, Safari 11+, Opera 44+
All credit goes to Bernard Widynski (author of the original paper).
Also, thanks to (Max Graey)[https://github.com/MaxGraey] for pointing out some code efficiency improvements.
🤩 Built with AssemblyScript 🤩
npm install squares-rng
In your project
let squares squares4 = ;
Browser (using global var)
After the npm installation simply include the script in your project:
A new global object will be available called
const squares squares4 = SquaresRNG;
; //=> 1083911291; //=> 1083911291; //=> 843037697; //=> 843037697// Need random numbers (as double floats) in [0,1] (including 0, but excluding 1)/ 0xffff_ffff; //=> 0.846250728435407/ 0xffff_ffff; //=> 0.08598547803377395/ 0xffff_ffff; //=> 0.4883159516584864/ 0xffff_ffff; //=> 0.3198446904588129/ 0xffff_ffff; //=> 0.23406353551756207
