r/RNG

I have hardware support for long integer operations. You can approximate it as BigInt(n) in JavaScript. I seek PRNG which can take advantage of this hardware support.

Proposed workflow - do some math using BigInt and then split result into byte array. User will pull randomness from that array. Obviously you can keep generator internal state in BigInts.

Probably combination of several LCG generators with post processing will do the job. This type of generator (combined LCG) is used in proprietary biology simulation software and gives same results in monte Carlo as slow Mersenne twister.

While MT produces better randomness during testsuites in real world monte carlo deployment that doesn't translates to more accurate results.
