Question

The range of intergers that can be represented by n bit 2's complement number system is

• A. $-2^{n-1}to(2^{n-1}-1)$
• B. $-(2^{n-1}-1)to(2^{n-1}-1)$
• C. $-2^{n-1}to{2}^{n-1}$
• D. $-(2^{n-1}+1)to(2^{n-1}-1)$

Answer 1

The correct option is A $-2^{n-1}to(2^{n-1}-1)$

The range is $-2^{n-1}to(2^{n-1}-1)$ including 0.
