How to remove decimal points in pandas
<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>
