(g) What is the range for this cell as written in binary and in decimal?

Explanation / Answer

5.

(a) The decimal to binary conversion of 51, assuming 9 bit 2's complement is

32+16+2+1 = 110011

(b) -29

The binary value of 29 is 11101

The binary inverse of 11101 is 11100011

As it is two digit we get,

11111111 11111111 11111111 11100011

(f) -1

The decimal number is 1 and the binary form of 1 is 1

The binary inverse is 0001

The answer is 0000 0000 0000 0001
