Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T).

1 Scope

This part of ISO/IEC 10967 specifies the properties of numerical approximations for complexarithmetic operations and many of the complex elementary numerical functions available in 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 document. 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.
