--- Comment #21 from Vittorio Zecca <zeccav at gmail dot com> --- If the cost is the same, this is a good reason to let the library handle this special case and let the programmer think about his/her business. Shouldn't system software ease the life of programmers? Shouldn't gfortran be consistent and raise the exception all the time, with integer real and complex exponent, or never? I mean, if the complex exponentiation has a (essential) singularity there, this is regardless of the Fortran type of the exponent. About portability, on my AMD 64 bit CPU with Fedora 18 I confirm that Intel ifort, NAG nagfor, and Solaris sunf95 do not raise any exception and deliver zero. A Fortran programmer may not know C and may think that a bad ** is a Fortran implementation issue. Anyway, I am preparing a note for the glibc people.
