title: What is the fastest int to float conversion on the iPhone?
body: <p>I am converting some Int16s and Int32s to float and then back again.</p>
  
  <p>I'm just using a straight cast, but doing this 44100 times per second (any guesses what its for? :) )</p>
  
  <p>Is a cast efficient? Can it be done any faster?</p>
  
  <p>P.S Compile for thumb is turned off.</p>
