  39                 To set the nth decimal place, give this field
  40                 the value of 10 ** n. Assume this field has
  41                 the value k and has 1 or more decimal places set,
  42                 to set the mth place (where m is not already set),
  43                 change this fields value to k + 10 ** m.
