title: Where are round(), rint() (and so on) C++ functions in Visual Studio 2012?
body: <p>These pages:</p>
  
  <p><a href="http://www.cplusplus.com/reference/cmath/round/">http://www.cplusplus.com/reference/cmath/round/</a></p>
  
  <p><a href="http://www.cplusplus.com/reference/cmath/rint/">http://www.cplusplus.com/reference/cmath/rint/</a></p>
  
  <p>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)?!</p>
  
  <p>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 <code>std::</code> and <code>tr1::</code> or another header file to get access to these?</p>
