CAN/CSA-ISO/IEC TR 15580-04

Scope

This Technical Report specifies an extension of the programming language Fortran, specified by the international standard ISO/IEC 1539-1:1997.

Its main aim is to provide support for the five exceptions of the IEEE standard for floating-point arithmetic, but it also provides support for other features of the IEEE standard.

A processor is permitted to provide partial support and there are facilities for enquiring about which features are supported or requiring support of certain features.

Clause 2 of this Technical Report contains a technical description of the features. It provides an overview and does not include all the fine details.

Clause 3 contains the editorial changes to the standard and thereby provides a complete definition.
