--- Comment #5 from Paolo Carlini <paolo.carlini at oracle dot com> 2011-10-14 14:56:27 UTC --- I haven't really followed this discussion, but I remember a very similar one some time ago, and I suspect that part of the confusion stems from the meaning of "finite-math": maybe some users don't consider calling std::is_nan part of a *mathematical computation* proper, they consider it something preliminary to it, they would like to see *only* arithmetic expressions, transcendental functions calls, etc, optimized per finite-math. I don't know if I have been able to explain myself well enough. Anyway, mine is just a side observation, maybe worth keeping in mind only when writing the documentation.
