Abstract

TypeScript implementations and comparison tests of popular pseudo random number generators.

Original JavaScript implementations were taken from https://github.com/bryc/code/blob/master/jshash/PRNGs.md.

Implementations

PRNGs

• Mulberry32
• sfc32
• SplitMix32
• Xoshiro128ss

Hash algorithms

• MurmurHash3 variant (xmur3)

Functionality

• random(from = 0, to = 1)
  • get a random number between "from" and "to" including this range
• gauss(m = 0, sd = 1)
  • get a normally distributed random number using the mean value (m) and the standard deviation (sd)
