title: python %precision magic function does not work for print()
body: <pre><code>%precision 2
      x = 2/3
      print(x)
  </code></pre>
  
  <p>this prints</p>
  
  <pre><code>0.6666666666666666
  </code></pre>
  
  <p>instead of</p>
  
  <pre><code>0.67
  </code></pre>
  
  <p>any idea why it does not work?
  I'm using ipython notebook
  Thanks</p>
