title: Scikit classification report - change the format of displayed results
body: <p>Scikit classification report would show precision and recall scores with two digits only. Is it possible to make it display 4 digits after the dot, I mean instead of 0.67 to show 0.6783?</p>
  
  <pre><code> from sklearn.metrics import classification_report
   print classification_report(testLabels, p, labels=list(set(testLabels)), target_names=['POSITIVE', 'NEGATIVE', 'NEUTRAL'])
                       precision    recall  f1-score   support
  
           POSITIVE       1.00      0.82      0.90     41887
           NEGATIVE       0.65      0.86      0.74     19989
           NEUTRAL        0.62      0.67      0.64     10578
  </code></pre>
  
  <p>Also, should I worry about a precision score of 1.00? Thanks!</p>
