title: Python: convert excel data into dataframes
body: <p>I want to put some data available in an excel file into a dataframe in Python.
  The code I use is as below (two examples I use to read an excel file):</p>
  
  <pre><code>d=pd.ExcelFile(fileName).parse('CT_lot4_LDO_3Tbin1')
  e=pandas.read_excel(fileName, sheetname='CT_lot4_LDO_3Tbin1',convert_float=True)
  </code></pre>
  
  <p>The problem is that the dataframe I get has the values with only two numbers after comma. In other words, excel values are like 0.123456 and I get into the dataframe values like 0.12.</p>
  
  <p>A round up or something like that seems to be done, but I cannot find how to change it.</p>
  
  <p>Can anyone help me?</p>
  
  <p>thanks for the help !</p>
