You may define an ordering relation where it is - in fact, there _is_ such an ordering defined already, and it is called "unsigned representation". You might perhaps find it useful, maybe even intersting, to read a little about number theory, specifically about cyclic number sets, modulo artihmetic, rest classes and the like. These are very important for digital data processing, not only for encryption, where these concepts are broadly employed, but even for the very mundane task of general calculations. E.g., given a 16 bit representation, add the numbers 32109 and 34567 correctly. Can you do it? Or multiply 1234 * 56. Equally interesting. -- -- (Weitergabe von Adressdaten, Telefonnummern u.ä. ohne Zustimmung nicht gestattet, ebenso Zusendung von Werbung oder ähnlichem) ----------------------------------------------------------- Mit freundlichen Grüßen, S.
