Device and method for evaluating inverse trigonometric functions

摘要

A method and device are provided for processing an input value to provide an output inverse trigonometric function value of the input value. It substantially comprises a method and device for modifying the input value to obtain an approximation value, determining at least one correction factor, generating at least one intermediate function value, being substantially an inverse trigonometric function value of the approximation value, and combining the intermediate function value with at least one correction factor to determine an output inverse trigonometric function value.
