1.1 Standards Conformance

• f95 conforms to part one of the ISO/IEC 1539-1:1997 Fortran standards document.

• Floating-point arithmetic is based on IEEE standard 754-1985, and international standard IEC 60559:1989.

• f95 provides support for the optimization-exploiting features of the SPARC and x86 families of processor architectures: UltraSPARC, SPARC64, AMD64, Pentium Pro, and Xeon Intel^®64, on Solaris and Linux (x86) platforms.

• Sun Studio compilers conform to the OpenMP 2.5 shared memory parallelization API specifications. See the OpenMP API User's Guide for details.

• In this document, “Standard” means conforming to the versions of the standards listed above. “Non-standard” or “Extension” refers to features that go beyond these versions of these standards.

The responsible standards bodies may revise these standards from time to time. The versions of the applicable standards to which these compilers conform may be revised or replaced, resulting in features in future releases of the Sun Fortran compilers that create incompatibilities with earlier releases.
