Description / Abstract:
This part of ISO/IEC 10967 speci es properties of many of the
integer and oating point datatypes available in a variety of
programming languages in common use for mathematical and numerical
applications.
It is not the purpose of this part of ISO/IEC 10967 to ensure
that an arbitrary numerical function can be so encoded as to
produce acceptable results on all conforming datatypes. Rather, the
goal is to ensure that the properties of the arithmetic on a
conforming datatype are made available to the programmer.
Therefore, it is not reasonable to demand that a substantive piece
of software run on every implementation that can claim conformity
to this part of ISO/IEC 10967.
An implementor may choose any combination of hardware and
software support to meet the speci cations of this part of ISO/IEC
10967. It is the datatypes and operations on values of those
datatypes, of 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 of ISO/IEC 10967)
denotes the total computing environment pertinent to this part of
ISO/IEC 10967, including hardware, language processors, subroutine
libraries, exception handling facilities, other software, and
documentation.
