Subtract (111000.110)2 - (110100.101)2 using both 2's and 1's complement.

Subtract $(111000.110)_2 - (110100.101)_2$ using both 2's and 1's complement. [5]

  • Minuend $A = (111000.110)2$ - Subtrahend $B = (110100.101)2$ - Format: 6 integer bits, 3 fractional bits. --- - $A = 111000.1102 = 56 + 0.75 = 56.75$ - $B = 110100.1012 = 52 + 0.625 = 52.625$ - $A - B = 4.125 = (100.001)2 = (000100.001)2$ So the expected answer is $(000100.001)2$. --- Step 1: 1...
