title: Round with integer division
body: <p>Is there is a simple, pythonic way of rounding to the nearest whole number without using floating point?  I'd like to do the following but with integer arithmetic:</p>
  
  <pre><code>skip = int(round(1.0 * total / surplus))
  </code></pre>
  
  <p>==============</p>
  
  <p>@John: Floating point is not reproducible across platforms.  If you want your code to pass tests across different platforms then you need to avoid floating point (or add some hacky espilon stuff to your tests and hope it works).  The above may be simple enough that it would be the same on most/all platforms, but I'd rather not make that determination as it is easier to avoid floating point altogether.  How is that "not in the spirit of Python"?</p>
