function randomSeeded(seed: bigint): Prng

Creates a pseudo-random number generator that generates random numbers in the range [0, 1), based on the given seed, with 32 bits of entropy. The algorithm used for generation is PCG32.

seed: bigint

The seed used to initialize the random number generator's state.

Returns

A pseudo-random number generator function, which will generate different random numbers on each call.
