¶*Standard*:Fortran 2003 and later

The `IEEE_EXCEPTIONS`

, `IEEE_ARITHMETIC`

, and `IEEE_FEATURES`

intrinsic modules provide support for exceptions and IEEE arithmetic, as
defined in Fortran 2003 and later standards, and the IEC 60559:1989 standard
(*Binary floating-point arithmetic for microprocessor systems*). These
modules are only provided on the following supported platforms:

- i386 and x86_64 processors
- platforms which use the GNU C Library (glibc)
- platforms with support for SysV/386 routines for floating point interface (including Solaris and BSDs)
- platforms with the AIX OS

For full compliance with the Fortran standards, code using the
`IEEE_EXCEPTIONS`

or `IEEE_ARITHMETIC`

modules should be compiled
with the following options: ```
-fno-unsafe-math-optimizations
-frounding-math -fsignaling-nans
```
