Abstract
An apparatus for evaluating a mathematical function at an input value is provided. The apparatus includes a device for selecting a mathematical function, a device for inputting a value at which to evaluate the function, a device for identifying an interval containing the input value, the interval being described by at least one polynomial function, a device for retrieving at least one control point representing the polynomial function from at least one look up table, a device for deriving the polynomial function from the control points, a device for evaluating the function for the input value and a device for providing data representing the evaluated function at an output.
