title: How are denormalized floats handled in C#?
body: <p>Just read this <a href="https://stackoverflow.com/a/9314926/1294758">fascinating article</a> about the 20x-200x slowdowns you can get on Intel CPUs with denormalized floats (floating point numbers very close to 0).</p>
  
  <p>There is an option with SSE to round these off to 0, restoring performance when such floating point values are encountered. </p>
  
  <p>How do C# apps handle this? Is there an option to enable/disable <code>_MM_FLUSH_ZERO</code>?</p>
