title: How to check if C++ compiler uses IEEE 754 floating point standard
body: <p>I would like to ask a question that follows <a href="https://stackoverflow.com/questions/752309/ensuring-c-doubles-are-64-bits">this one</a> which is pretty well answered by the define check if the compiler uses the standard. However this woks for C only. Is there a way to do the same in C++? </p>
  
  <p>I do not wish to covert floating point types to text or use some pretty complex conversion functions. I just need the compiler check. If you know a list of such compatible compilers please post the link. I could not find it.</p>
