Actually it's a design issue. C uses a numeric datatype that is bound by a specific number of bits. It could just have well have been designed with a numeric datatype that had arbitrary length. The design decision was made to keep it close to the machine. However, the point I was making is that dealing with fringe cases is a necessity when you want to ensure your code is robust. > PS: It's a little bit rude to say "you *must* have missed" but I understand > that it wasn't your intention.
