I take it that you are using python3.x rather than python2.x. In python 2.x, the expression 100/25 is the integer 4 In python 3.x, the expression 100/25 is 4.0 And as someone already pointed out mixing Decimal and float doesn't work.
Try replacing the 100 / 4 with one of int(100/4) or (100//4) (yes, two slashes does integer divide) or Decimal(str(100/4)), or try the original examples in a python2.x version where the single slash operator still returns an int if both arguments are int.
