Sec. 1. If a computation under this article results in a fraction and a rounding rule is not specified, the fraction shall be rounded as follows:
(1) All calculations related to the complexity index shall be computed by rounding to the nearest ten thousandth (0.0001).
(2) All tuition support distributions shall be computed by rounding the levy or tuition support distribution to the nearest dollar ($1) amount.
(3) The fraction calculated in IC 20-43-2-4 shall be computed by rounding to the nearest one millionth (0.000001).
(4) If a calculation is not covered by subdivision (1), (2), or (3), the result of the calculation shall be rounded to the nearest one hundredth (0.01).
