title: How to remove decimal points in pandas
body: <p>I have a pandas data frame, df, which looks like this:</p>
  
  <pre><code>Cut-off             &lt;=35   &gt;35                   
  Calcium              0.0   1.0
  Copper               1.0   0.0
  Helium               0.0   8.0
  Hydrogen             0.0   1.0
  </code></pre>
  
  <p>How can I remove the decimal point so that the data frame looks like this:</p>
  
  <pre><code>Cut-off             &lt;= 35  &gt; 35                   
  Calcium              0     1
  Copper               1     0
  Helium               0     8
  Hydrogen             0     1
  </code></pre>
  
  <p>I have tried <code>df.round(0)</code> without success.</p>
