title: defining precision in python(2.6) division
body: <p>from <strong>future</strong> import division
  To perform a division in which I need some percision. However, it gives a long number, like: </p>
  
  <pre><code>1.876543820098765
  </code></pre>
  
  <p>I only need the the first two numbers after "." => 1.87
  How can I do that?</p>
