IEEE_EXCEPTIONS
, IEEE_ARITHMETIC
, and IEEE_FEATURES
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:
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
