Abstract
A system and method for accurately calculating a mathematical power function in an electronic device may include an application program that is configured to calculate a direct estimate of power function value for the mathematical power function during a direct linear interpolations procedure. The application program may also calculate an indirect estimate of power function value for a complement power function during an indirect linear interpolation procedure. The application program may then perform a final function-estimate calculation procedure to accurately produce a final estimated power function value from the foregoing direct estimate of power function value and indirect estimate of power function value.
