title: How to save integers in int format in dataframe.to_csv()?
body: <p>I have created a dataframe with values from a list like below: </p>
  
  <pre><code>myDataframe= pd.DataFrame({ key:pd.Series(value) for key, value in myList.items() }).fillna('')
  </code></pre>
  
  <p>I have some IDs in a dataframe which are like 45333, 4556676. So, when I save this dataframe to a csv file using to_csv() function,but it saves it as 45333.0, 4556676.0 rather than 45333. </p>
  
  <p>Below is the code: </p>
  
  <pre><code>export_csv = myDataframe.to_csv (r'/home/myData/new.csv', index = None, header=True) 
  </code></pre>
  
  <p>I tried to add <code>float_format = none</code>in the <code>to_csv()</code> function. But, this has no effect. </p>
  
  <p>Can someone please tell me what the issue is?
  I need to save those ids in the form it is in. Not extra float bytes.  </p>
