Administrator Registered: 2000-01-24 Posts: 4946 Loc: Leatherhead, Surrey, UK	Heh, no, that actually ignores the issue What I'm talking about is (for example) binary representation of a negative number. Normally twos-complement - I don't think ones-complement is much used. For example the offset for time zones is sometimes negative, which is stored in the registry as a twos-complement value. That's why in my recommendation there is an optional word size - you need to know how wide the target is to construct a twos-complement value.
