Detailed Description

xorshift128+

Member Function Documentation

next() [1/2]

template<>

uint64_t tt::xorshift128p::next ( )

inlinenoexcept

Get the next 64 bit of random value.

next() [2/2]

template<>

u64x2 tt::xorshift128p::next ( )

inlinenoexcept

Get next 128 bit of random value.

The algorithm is based around next64(), it was modified to do two consecutive iterations and then merging those using sse instructions.
