Abstract
This paper describes a simple and accurate floating-point reciprocal algorithm based on two modified Newton-Raphson iterations with a magic constant as the initial approximation. It can be effectively implemented on platforms with no FPU support since it uses just addition, multiplication and fused multiply-add operations.
