Where is isnan() in MSVC 2010?
<p>I'm trying to write a program which uses <code>std::isnan()</code> with MSVC 2010. I include <code>cmath</code> but unfortunately the compiler returns the error: </p>

<blockquote>
  <p>isnan is not part of the std namespace</p>
</blockquote>

<p>Does MSVC 2010 support this function from std (AKA C++11)?</p>
