Signed Integers Historically: 3 approaches could be used. Sign-and-magnitude Ones-complement Twos-complement For all 3, the most-significant bit (MSB) is the sign digit 0 ≡ positive 1 ≡ negative Twos-complement is the important one (Simplifies arithmetic - Used almost universally)...
Signed Integers Historically: 3 approaches could be used. Sign-and-magnitude Ones-complement Twos-complement For all 3, the most-significant bit (MSB) is the sign digit 0 ≡ positive 1 ≡ negative Twos-complement is the important one (Simplifies arithmetic - Used almost universally) Signed Integers Signed Integers Signed Integers Get the representation of ones complement (6 bit) for the following numbers: i) +710 ii) –1010 Solution: Solution: (+7) = 0001112 (+10)10 = 0010102 So, (-10)10 = 1101012
