Question

n/a

Answer 1

1 0 0 0 1 1 0 0 1
256 128 64 32 16 8 4 2 1

Above is the binary you specified, with the( 2^nth) power to the equivalent bit below.

For an unsigned integer = 256 + 16 + 8 + 1
For a signed integer in sign-magnitude notation = -(16 + 8 + 1)

--For the next one, since it is in twos complements i have to reverse it to get the real number. (I am not 100% sure that this is correct)
For a signed integer in two’s complement notation = 128 + 64 + 32 + 4 + 2

Answer 2

thanks!!!
