Moving a small C++ project from XCode to Visual studio. Ceiling/floor unrecognized?
<p>I have a small c++ project I've been working on in XCode, that I'd like to do some work with on my Windows machine, on Visual Studio.  I made a new project and copied all of the source files into the new project.  There are no external dependencies.</p>

<p>Now, Visual Studio does not like any of my floor or ceil calls.  I get the following compiler error for every call to ceil or floor.</p>

<blockquote>
  <p>'ceil': ambiguous call to overloaded
  function</p>
</blockquote>

<p>These functions are not overloaded, and I've imported math.h in the header file to this .cpp file.  What gives?</p>
