title: C/C++: Float comparison speed
body: <p>I am checking to make sure a float is not zero. It is impossible for the float to become negative. So is it faster to do this <code>float != 0.0f</code> or this <code>float &gt; 0.0f</code>?</p>
  
  <p>Thanks.</p>
  
  <p>Edit: Yes, I know this is micro-optimisation. But this is going to be called every time through my game loop, and I would like to know anyway.</p>
