Question 2

What is R's complement and (R-1)'s complement?

Accepted Answer

For a number system with radix R, the (R-1)'s complement is found by subtracting every digit from (R-1). The R's complement is found by adding 1 to the least significant digit of the (R-1)'s complement. For binary these are called 1's complement and 2's complement.
