Currently, I'm revising all of the math pages in man-pages, and in the process testing the error handling (glibc 2.8) for each function. I find the following: a) on error, many (probably a majority of) functions set errno AND raise an exception (fetestexcept()). b) on error, a very few functions DO set errno but DON"T raise an exception (fetestexcept()). c) on error, a few functions DON'T set errno but DO raise an exception (fetestexcept()). d) on error, a very few functions pursue a mixture of all of the above, depending on the error. A math_error(7) page that I recently wrote (see http://www.kernel.org/doc/man-pages/online/pages/man7/math_error.7.html ) currently implies that all functions should do a). Clearly I'll need to amend that. But the main question is, should I raise glibc bugs for the functions in cases b), c), and d)?
