\brief \b ESMF_IEEECK \htmlonly Download ESMF_IEEECK + dependencies [TGZ] [ZIP] [TXT] \endhtmlonly \par Purpose:
\verbatim
ESMF_IEEECK is called from the ESMF_ILAENV to verify that Infinity and possibly NaN arithmetic is safe (i.e. will not trap). \endverbatim \param[in] ISPEC \verbatim ISPEC is INTEGER Specifies whether to test just for inifinity arithmetic or whether to test for infinity and NaN arithmetic. = 0: Verify infinity arithmetic only. = 1: Verify infinity and NaN arithmetic. \endverbatim
\param[in] ZERO \verbatim ZERO is REAL Must contain the value 0.0 This is passed to prevent the compiler from optimizing away this code. \endverbatim
\param[in] ONE \verbatim ONE is REAL Must contain the value 1.0 This is passed to prevent the compiler from optimizing away this code.
RETURN VALUE: INTEGER = 0: Arithmetic failed to produce the correct answers = 1: Arithmetic produced the correct answers \endverbatim \author Univ. of Tennessee \author Univ. of California Berkeley \author Univ. of Colorado Denver \author NAG Ltd. \date November 2011 \ingroup auxOTHERauxiliary
