I think your problem is that "the number of digits a number has" is not a property of the number (since the numbers 8.00 and 8 are the same number). You need to keep track of the digits in some other way. One possibility is to store two numbers: the lowest possible value and the highest possible value. Then 8.00 would be stored as (7.995, 8.005). It's then possible (but not easy) to propagate these ranges through transformations.
