'''Ones' complement''', two's a crowd. Ones' compliment is a binary system in which the negative of a number is formed by inverting all its bits, in distinction from [[Two's complement]], where one is added to this inversion to produce the final result. In ones' compliment notation, there is both a positive and a negative zero; two's complememnt avoids this and makes it possible to express one more negative number than positive (which is why 16-bit signed integers can range from -32768 to 32767 in two's complement but only -32767 to 32767 in ones' complement).

Some old computer models used ones' complement, but most modern systems use two's complement.
