ISO/IEC 10967-2:2001

This part of ISO/IEC 10967 de_nes 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 speci_cations of this part. It is the computing environment, as seen by the programmer/user, that does or does not conform to the speci_cations. 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.
