Detailed Description

xoroshiro128+.

Very fast, not-cryptographic random number generator. From https://prng.di.unimi.it/ Example:

std::random_device rd;
random::Xoroshiro128Plus rng(rd(), rd());
uint64_t r = rng();

std::uniform_real_distribution<float> uniform(0.f, 1.f);
float r = uniform(rng);

std::normal_distribution<> normal(0.0, 1.0);
double r = normal(rng);
