<p>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 comprising a modifier (104) for modifying the input value to obtain an approximation value, a correction factor generator (108) for determining at least one correction factor, a first function generator (106) for generating at least one intermediate function value, being substantially an inverse trigonometric function value of the approximation value, and a combiner (110) for combining the intermediate function value with at least one correction factor to determine an output inverse trigonometric function value.</p> |
