Functions

func XoRoShiRo128SS

func XoRoShiRo128SS(s0, s1 uint64) (uint64, uint64, uint64)

XoRoShiRo128SS calculates predictable pseudorandom number with XOR/rotate/shift/rotate 128** (xoroshiro128starstar) algorithm. In some cases a little faster than XorShift64S, but uses 128 bits footprint. see https://prng.di.unimi.it/xoroshiro128starstar.c

func XorShift64S

func XorShift64S(s uint64) (uint64, uint64)

XorShift64S calculates predictable pseudorandom number with XOR/Shift 64* (shorshift64*) algorithm. see https://vigna.di.unimi.it/ftp/papers/xorshift.pdf
