Description
Header-only library for division via fixed-point multiplication by inverse.
On modern CPUs and GPUs integer division is several times slower than multiplication. FXdiv implements an algorithm to replace an integer division with a multiplication and two shifts. This algorithm improves performance when an application performs repeated divisions by the same divisor.
Features: * Integer division for uint32_t, uint64_t, and size_t * Header-only library, no installation or build required * Compatible with C99, C++, OpenCL, and CUDA * Uses platform-specific compiler intrinsics for optimal performance * Covered with unit tests and microbenchmarks
