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.
