There is provided a method and apparatus for processing an input value to provide an output exponential value of a desired base raised to the power of the input value. It comprises a first adjuster (102) for adjusting the input value, a predetermined base of a first exponential value, and the desired base of the output exponential value to obtain a first scaled value, a modifier (104) for modifying to obtain an approximation value, a first function generator for determining the first exponential value of the approximation value, an error adjuster (106) for generating an adjusted error value, the approximation value, and a logarithm of the predetermined base of the first exponential value, a correction generator (110) for determining a correction value for the first exponential value, and a combiner (112) combining the first exponential value with the correction value. |
