title: What is the fastest way to convert float to int on x86
body: <p>What is the fastest way you know to convert a floating-point number to an int on an x86 CPU.  Preferrably in C or assembly (that can be in-lined in C) for any combination of the following:</p>
  
  <ul>
  <li>32/64/80-bit float -> 32/64-bit integer</li>
  </ul>
  
  <p>I'm looking for some technique that is faster than to just let the compiler do it.</p>
