Explanation / Answer
Here the following are the answers for your questions
(1)What bit pattern would represent the decimal number -89 in the following format?
Signed magnitude: 11011001
One's complement: 10100110
Two's complement: 10100111
Excess-127 : 0100110
(2)
What decimal values does the 8-bit binary number 10110100 have if:
It is interpreted as an unsigned number?
Signed-magnitude representation: -76
One's complement representation: -75
Two's complement representation: -76
(3)
Given the following two binary numbers: 11111100 and 01110000
11111100 is the larger unsigned binary number.
01110000 is the larger when it is being interpreted on a computer using signed two's complement representation.
11111100 is the smaller when it is being interpreted on a computer using signed-magnitude representation?
(4)
Subtract the following signed binary numbers using 2's complement arithmetic:
11000100 - 00111011 = 11000001
11000100 - 00111011 =193(Result in decimal)
(5) Using arithmetic shifting what is the result of dividng the value 110010102 in half?
The Answer is : 01100101
