Description

The hypot family of functions from math.h does not appear in the std namespace when #including the header <cmath>, as specified in section 17.6.1.2 of the C++ standard. There may be other similar oversights; a quick glance shows that cbrt is also not present.

Hi,

Thanks for reporting this bug. We've fixed it, and the fix will be available in VC11.

I checked, and hypot()/hypotf() were the only C99 math functions implemented in VC that weren't being dragged into namespace std by <cmath>. Now they are.

Please note that while the C++11 Standard Library includes the C99 Standard Library by reference, and we've already implemented <stdint.h>, we didn't have time to implement even more of the C99 Standard Library in VC11. However, given that we already had hypot()/hypotf(), it was an extremely simple matter to add them to <cmath>.

If you have any further questions, feel free to E-mail me at stl@microsoft.com .
