A pseudorandom number generator (PRNG) is an algorithm used to generate a sequence of numbers whose attributes approximate the attributes of sequences of random numbers. The sequence generated by PRNG is not truly random, because it is determined entirely by the initial value of a seed called PRNG. Here, a PRNG based on XOR/shift/rotate called xoshiro128 is implemented. Its algorithm comes from `PRNG`_.
