multiplyAndSplit64to32()

ALPAKA_FN_HOST_ACC constexpr void alpaka::rand::multiplyAndSplit64to32 ( std::uint64_t const  a, std::uint64_t const  b, std::uint32_t &  resultHigh, std::uint32_t &  resultLow  )

inlineconstexpr

Multiply two 64-bit numbers and split the result into high and low 32 bits, also known as "mulhilo32"

Parameters

a	first 64-bit multiplier
b	second 64-bit multiplier
resultHigh	high 32 bits of the product a*b
resultLow	low 32 bits of the product a*b
