Abstract
A new algorithm for computing the complex logarithm and exponential fu nctions is proposed. This algorithm is based on shift-and-add elementa ry steps, and it generalizes some algorithms by Briggs and De Lugish, as well as the Cordic algorithm. It can easily be used to compute the classical real elementary functions (sin, cos, arctan, In, exp). This algorithm is more suitable for computations in a redundant number syst em than the Cordic algorithm, since there is no scaling factor when co m tin trigonometric functions.
