title: Test if a floating point number is an integer
body: <p>This code works (C# 3)</p>
  
  <pre><code>double d;
  if(d == (double)(int)d) ...;
  </code></pre>
  
  <ol>
  <li>Is there a better way to do this?</li>
  <li>For extraneous reasons I want to avoid the double cast so; what nice ways exist other than this? (even if they aren't as good)</li>
  </ol>
  
  <p><em>Note:</em> Several people pointed out the (important) point that == is often problematic regrading floating point. In this cases I expect values in the range of 0 to a few hundred and they are supposed to be integers (non ints are errors) so if those points "shouldn't" be an issue for me.</p>
