Abstract : The proposed standard for the Generic Package of Primitive Functions (GPPF) for Ada represents the work of a large number of people in both the United States and Europe who have collaborated to develop specifications for packages of Ada mathematical functions. GPPF is the specification for primitive functions and procedures for manipulating the fraction part and exponent part of machine numbers of the generic floating-point type. Additional functions are provided for directed rounding to a nearby integer for computing an exact remainder, for determining the immediate neighbors of a floating- point machine number for transferring the sign from one floating-point machine number to another and for shortening a floating-point machine number to a specified number of leading radix digits.
