适用范围：This part of ISO/IEC 10967 specifies the properties of numerical approximations for complex arithmetic 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. Inclusions The specifications of part 1 and part 2 are included by reference in this part. This document provides specifications for properties of complex and imaginary integer datatypes and floating point datatypes, basic operations on values of these datatypes as well as for some numerical functions for which operand or result values are of imaginary or complex integer datatypes or imaginary or complex floating point datatypes constructed from integer and floating point datatypes satisfying the requirements of part 1 (ISO/IEC 10967-1). 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 (not-anumber), is prescribed for each specified floating point operation. This document provides specifications for: a) Basic imaginary integer and complex integer operations. b) Non-transcendental imaginary floating point and Cartesian complex floating point operations. c) Exponentiation, logarithm, radian trigonometric, and hyperbolic operations for imaginary floating point and Cartesian complex floating point. This document also provides specifications for: d) The results produced by an included floating point operation when one or more operand values include IEC 60559 special values. e) Program-visible parameters that characterise certain aspects of the operations.
