This part of ISO/IEC 10967 defines the properties of numerical approximations for many of the real elementary numerical functions available in standard libraries for a variety of programming languages in common use for mathematical and numerical applications.
An implementor may choose any combination of hardware and software support to meet the specifications of this part. It is the computing environment, as seen by the programmer/user, that does or does not conform to the specifications.
The term implementation (of this part) denotes the total computing environment pertinent to this part, including hardware, language processors, subroutine libraries, exception handling facilities, other software, and documentation.
Inclusions
The specifications of part 1 are included by reference in this part.
This part provides specifications for numerical functions for which all operand values are of integer or floating point datatypes satisfying the requirements of part 1. Boundaries for the occurrence of exceptions and the maximum error allowed are prescribed for each specified operation. Also the result produced by giving a special value operand, such as an infinity, or a NaN, is prescribed for each specified floating point operation.
This part covers most numerical functions required by the ISO/IEC standards for Ada [11], Basic [16], C [17], C++ [18], Fortran [22], ISLisp [24], Pascal [27], and PL/I [29]. In particular, specifications are provided for:
This part also provides specifications for:
Exclusions
This part provides no specifications for
Furthermore, this part does not provide specifications for how the operations should be implemented or which algorithms are to be used for the various operations.
