I suggest that you get hold of a good 1960s or 1970s book on computer arithmetic, and read up about "wobbling precision". While it is not a big deal, it was regarded as such, and is important enough to cause significant numerical problems to the unwary - which means 99.99% of modern programmers :-( And, as I am sure that Aahz could point out, there are significant reliability issues concerned with frequent base changes where any loss of precision is unacceptable. Yes, it can always be done, but only a few people are likely to do it correctly in all cases.
