Define IEEE_IS_NAN, IEEE_IS_FINITE, & IEEE_REM. Differential Revision: https://reviews.llvm.org/D100599
Due to architectural variation on the C++ functions std::ceil, std::floor, and std::trunc, diable some new Fortran unit tests for now that depending on specifical results for IEEE floating-point edge cases of infinities and NaNs.
A new unit test for the Fortran runtime needs to allow for some architectural variation on Infinity and NaN edge cases of NINT().
Adds APIs, implementations, and unit tests for AINT, ANINT, CEILING, EXPONENT, FLOOR, FRACTION, MOD, MODULO, NEAREST, NINT, RRSPACING, SCALE, SET_EXPONENT, & SPACING. Differential Revision: https://reviews.llvm.org/D99764
