I'm adding an "unsigned" option to the XInt library, so that fixed-length integers act exactly like their built-in counterparts. That in itself is not a problem, since unsigned fixed-length integers have a well-known and standard behavior.
The problem is: what should the library do if the user asks for an unsigned *non*-fixed-length integer?
Can anyone think of a potential reason for options C or D? Or a reason to prefer option B? Or maybe come up with a different idea entirely?
What about making the difference between two unsigned integers a signed integer? Regards, Vicente
