4.6.2 IEEE Floating-Point Exception Handling

New intrinsic modules IEEE_ARITHMETIC, and IEEE_FEATURES provide support for exceptions and IEEE arithmetic in the Fortran language. Full support of these features is provided by:

USE, INTRINSIC :: IEEE_ARITHMETIC

USE, INTRINSIC :: IEEE_FEATURES

The INTRINSIC keyword is new in Fortran 2003.These modules define a set of derived types, constants, rounding modes, inquiry functions, elemental functions, kind functions, and elemental and non-elemental subroutines. The details are contained in Chapter 14 of the Fortran 2003 standard.
