Given a binary number
x, the number NOT
(x) is called the 1's complement
of x. The NOT operator
when applied on a bit reverses the 'truth
' of the bit i.e.
Not(TRUE)=FALSE and Not(FALSE)=TRUE
NOT(1)=0 and Not(0)=1
We extend the NOT operator to a multi-bit value, so that Not(x) is the value with all its bits reversed.
So, the 1's complement
the binary number
