Removed an old way of doing rounding where it multiplied by 100, converted to an int, and then divided by 100.
While doing that I also added variable precision to the error message so you don't end up with -0.00.
Adding the variable precision meant also changing the previously hard coded PLR line to also used variable precision, so the table would line up.
