Ah OK, fair enough. Where should the tests go? The only tests I could find for the existing (non -f/l) functions was just tests for their existence in testsuite/26_numerics/headers/cmath/functions_std_c++17.cc which I just added the new functions to - I guess I'll add a new file here and test that all the functions can be called and give the same results as the relevant overloaded variants?
