title: What does >> and 0xfffffff8 mean?
body: <p>I was told that <code>(i &gt;&gt; 3) is faster than (i/8)</code> but I can't find any information on what <code>&gt;&gt;</code> is.  Can anyone point me to a link that explains it?  </p>
  
  <p>The same person told me "<code>int k = i/8</code>, followed by <code>k*8</code> is better accomplished by <code>(i&amp;0xfffffff8);</code>" but again Google didn't help m...</p>
  
  <p>Thanks for any links!</p>
