Fast 64-bit PRNG based on the xoshiro256** algorithm. More...

#include <rng-utils.hpp>

Public Types¶

Type	Name
typedef uint64_t	result_type

Public Functions¶

Type	Name
	epi_xoshiro256ss (uint64_t seed_val=0) noexcept
result_type	operator() () noexcept
void	seed (uint64_t seed_val) noexcept

Public Static Functions¶

Type	Name

constexpr result_type	min () noexcept

Detailed Description¶

xoshiro256** has 256-bit state, 64-bit output, and passes all known statistical tests. It is significantly faster than std::mt19937. State is seeded via SplitMix64 from a single 64-bit value.
