Regarding `errno`: it's totally valid to ignore if the implementation sets `math_errhandling & MATH_ERRNO` to zero. Of course, you need to know the C library to make that choice, but its value never changes at runtime. See C11 section 7.12, as well as the soon-to-be-published C++ paper p0108r1 <http://wg21.link/p0108r1> which you can preview here <https://github.com/paulmckrcu/TLSproposal-P0108/blob/master/TLSproposal.html>.
