A method and apparatus for implementing adaptive forward differencing technique in integer arithmetic resulting in an increase in precision while minimizing the number of mathematical operations to be performed is disclosed. The method and apparatus of the present invention provides for using a floating binary point adaptive forward differencing technique in which the binary point of the forward difference register containing the value of theparametric function is not shifted during parameter adjust-up and adjust-down operations. The binary point of the succeeding forward difference registers each containing a value corresponding to succeeding higher order derivatives of the parametric …
