  • Method and apparatus for implementing adaptive forward differencing using integer arithmetic
    Patent number: 5179647
    Abstract: 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 the parametric function, is not shifted during parameter adjust-up and adjust-down operations.
