摘要： A method for a processor computing a first trigonometric function to use an alternative trigonometric function for certain ranges of the operand. A modulo function may be used to provide an operand with a reduced range, and the modulo function may subtract in multiple steps in a manner that preserves low-order bits.

摘要： Computers and methods for performing mathematical functions are disclosed. An embodiment of a computer includes an operations level and a driver level. The operations level performs mathematical operations. The driver level includes a first lookup table and a second lookup table, wherein the first lookup table includes first data for calculating at least one mathematical function using a first level of accuracy. The second lookup table includes second data for calculating the at least one mathematical function using a second level of accuracy, wherein the first level of accuracy is greater than the second level of accuracy. A driver executes either the first data or the second data depending on a selected level of accuracy.
