|
|
<p>The <code>IEEE_EXCEPTIONS</code>, <code>IEEE_ARITHMETIC</code>, and <code>IEEE_FEATURES</code>
|
|
intrinsic modules provide support for exceptions and IEEE arithmetic, as
|
|
defined in Fortran 2003 and later standards, and the IEC 60559:1989 standard
|
|
(<em>Binary floating-point arithmetic for microprocessor systems</em>). These
|
|
modules are only provided on the following supported platforms:
|
|
</p>
|
|
<ul>
|
|
<li> i386 and x86_64 processors
|
|
</li><li> platforms which use the GNU C Library (glibc)
|
|
</li><li> platforms with support for SysV/386 routines for floating point
|
|
interface (including Solaris and BSDs)
|
|
</li><li> platforms with the AIX OS
|
|
</li></ul>
|
|
|
|
<p>For full compliance with the Fortran standards, code using the
|
|
<code>IEEE_EXCEPTIONS</code> or <code>IEEE_ARITHMETIC</code> modules should be compiled
|
|
with the following options: <code>-fno-unsafe-math-optimizations
|
|
-frounding-math -fsignaling-nans</code>.
