The tests are inconsistent with the statement of the problem. Finite strings like ..123451234512345 only repeat to the end of the string, then switch to zeros.
If the number is a true repeater, then multiplying it by 999... for some number of 9's will result in an integer. The difficulty lies in the rounding. I had to tune the tolerance to deal with cases like .123451234512345, which aren't truly repeating.
Some cleaning up!
