chrisakroyd/random-seedable

Fully-fledged random number generator library with high quality implementations of Xorshift, Xorwow, Mersenne Twister, PCG and LCG. Each implements a standard API producing number distributions that exactly match the original implementations.

random-seedable's Issues

documentation doesn't match function for `randRange`

Documentation says randRange is "inclusive" for 'min' and "inclusive" for 'max', but on running thousands of iterations it seems it is actually exclusive of 'max'.

Using XORWow

random.randRange(min, max)

Generates a number within the given range.

Parameters
min -> Lower bound of the numbers to generate (inclusive).
max -> Upper bound of the numbers to generate (inclusive).
Returns
Number min <= Number <= max.

Readme says XorShift but it should be XORShift (uppercase)

Otherwise imports fail

"fork"

I am using your code in a mono-repo and I've forked it only to resolve some incomplete typing issues.
I don't really want to maintain a fork.
Nevertheless, if you want to backport anything out of my "fork"- it is located https://github.com/Digital-Defiance/nx-monorepo/tree/main/digital-defiance/libs/random-seedable-ts

Infinite loop when changing seed of XORShift, then calling random.randBelow(N)

I have a program working fine but adding these two lines produces an infinite loop:

random.seed = 5555;
console.log(random.randBelow(10));

If I remove any of the two lines it works fine.

Replacing XORShift with PCG also solves the issue.

Running on Chromium Version 110.0.5481.177 (Official Build) Arch Linux (64-bit).

Any idea why this could happen? I'll try to create a reproducible program when I get a moment.
