According to the documentation, the whole point of having NSDecimalNumbers is to do base-10 arithmetic. I see nothing in there about preserving precision, neither in reference to the design intent nor in reference to the implementation. Perhaps I missed something? Times like this I wonder if I am the only one who consults documentation before posting....
