Use the Xoroshiro128PlusPlus class to represent a pseudo-random number generator that uses the Xoroshiro128++ algorithm by David Blackman and Sebastiano Vigna.

This generator has a period of 2¹²⁸ - 1 and passes all statistical tests. It is faster than the xoshiro256 family but with a smaller state space, making it ideal for applications that need speed but don't require the longest period.

The "++" scrambler provides excellent statistical quality suitable for all purposes except for generating more than 2⁶⁴ random numbers without jumping.
