title: Integers from excel files become floats?
body: <p>I use <code>xlrd</code> to read data from excel files.</p>
  
  <p>For integers stored in the files, let's say <code>63</code>, the <code>xlrd</code> interprets it as <code>63.0</code> of type <code>number</code>. </p>
  
  <p>Why can't <code>xlrd</code> recognize <code>63</code> as an integer? </p>
  
  <p>Assume <code>sheet.row(1)[0].value</code> gives us <code>63.0</code>. How can I convert it back to <code>63</code>.</p>
