Abstract
A method for approximating mathematical functions using polynomial expansions is implemented in a numeric processing system. A partial remainder operation is set forth for high accuracy reduction of polynomials whose arguments are greater than pi/4. The method may be practiced in a processor having a bus of approximately half the width of the precision of the desired result. Temporary registers are utilized for the storage of intermediate results. Full bus width accuracy is obtained through successive half bus width operations.
