A device for generating the value of the sine and cosine functions for angles between 0 DEG and 360 DEG is disclosed herein. By employing the symmetrical characteristics of the sine and cosine functions, a table of values for the sine function between 0 DEG and 90 DEG is the extent of the memory requirements. A read-only memory is disclosed for storing the table of values, and peripheral circuitry is provided for translating from the sine to the cosine functions as well as translating to angles between 90 DEG and 360 DEG for both functions. Additional circuitry is disclosed for providing the resultant output value in true binary form, or two's complement form.
