Agreed that there are other ways, almost certainly. I was going with the assumption that we wanted to store positional values for that question.
That is, it is only when you assume that you have to write out all decimal digits that you get people writing silly things that computers do all of the time. "0.66666...7" is an easy example. Ironically, to me, is that in written assignments you likely would have gotten knocked off points for not writing 0.(6) where () means an overbar. You definitely would lose points for rounding at the end.
