title: Formatting a cell to a percentage in PHPExcel
body: <p>I am automating an excel spreadsheet using PHP.</p>
  
  <p>I have been looking for a way to pragmatically format a cell to a percentage in PHPExcel.</p>
  
  <p>I want to change a value like </p>
  
  <blockquote>
    <p>0.077922078</p>
