title: Is floating point types usage prohibited on Android
body: <p>A page on the Android developer's site mentions that you should (quote): "Avoid Using Floating-Point" (link: <a href="http://developer.android.com/training/articles/perf-tips.html#AvoidFloat" rel="nofollow">Performance Tips</a>)</p>
  
  <p>After reading the whole article, it seems that some of the items there may be a bit outdated (perhaps written a few years ago).</p>
  
  <p>I would like to know whether this guideline is still valid today, or whether it is really bad (x2 performance hit, even on today's hardware) to use floating point types?</p>
