Signed Number System In signed number systems, a number is represented with two parts; one the sign bit, and the rest bits denote the magnitude of the number. Signed number are represented using the following representation: Sign and Magnitude number system: 1's complement Number System 2's Complement Number System Sign and Magnitude number system In this system, the MSB is set to 0(zero) to indicate +ve number and is set to 1(one) to indicate the -ve number. Signed numbers are represented as: Complete the following Table +7 Sign Magnitude +7 0 1 1 1 -6 1 1 1 0 +25 -24 +14 -15 -10 +0 -0 Complement method: Complement of a number: Complement of a number is done to represent its -ve / or positive representation. Thus the complement of a +ve number is the -ve number, and complement of -ve number is +ve number. There are different types of
