The Problem Convert 256 to its 2's complement representation.
I know that 256's representation in unsigned binary is 100000000. What I know from working with two's complement model is that the most significant digit represents the sign of the number. So in this case, 100000000 cannot be 2's complement representation as well because that would mean that the original number, 256 is negative.
Is there a specified number of zeros I should add to the front of the binary representation? Would it be acceptable to just add one zero to the front, say 0100000000?
