Answer:
-10
Explanation:
Given hex number = 0x FFF6
Converting it to binary: 1111111111110110
Generating 1s complement of the binary representation by inverting the bits :
0000000000001001
Adding 1 to generate the 2's complement :
0000000000001001 + 1 = 0000000000001010
Converting it to decimal , this corresponds to 10
So the 2s complement of original number is 10. This means that the original number is -10.
