Explain how to determine if a number is negative in each of thefollowing representations: sign magnitude, twos complement,biased.
Answer
In sign-magnitude representation, the left most bit is used torepresent the sign. If it is 1, it is a negative number. If it is0, it is a positive number. The rest of the bis are used torepresent the magnitude of the number.
For example -2410 is represented as 1 001 1000. The leftmost bit 1( 1 ) represents,it is a negative number. The remaining 7 bits shows the magnitude24.
In two’s complement representation also, the left most bitrepresents the sign. If it is
