title: Panda Python - dividing a column by 100 (then rounding by 2.dp)
body: <p>I have been manipulating some data frames, but unfortunately I have two percentage columns, one in the format '61.72' and the other '0.62'.</p>
  
  <p>I want to just divide the column with the percentages in the '61.72' format by 100 then round it to 2.dp so it is consistent with the data frame.</p>
  
  <p>Is there an easy way of doing this?</p>
  
  <p>My data frame has two columns, one called 'A' and the other 'B', I want to format 'B'.</p>
  
  <p>Many thanks!</p>
