Where are round(), rint() (and so on) C++ functions in Visual Studio 2012?

Question

These pages:

http://www.cplusplus.com/reference/cmath/round/

http://www.cplusplus.com/reference/cmath/rint/

imply that these functions are part of C++11, and Visual Studio 2012 seems to support basically everything in C++11... so where the heck are the rounding functions (not to mention the other additional math functions)?!

I know all about rolling my own rounding function, but it just seems ridiculous at this point. Am I just missing something here and there's some special combination of std:: and tr1:: or another header file to get access to these?

Answer 1

As you say, VS2012 supports "basically everything" from C++11, but that is not the same as "everything".

These functions were added in VS2013 which, for the record, still doesn't support "everything".
