If the sum of two … WebIn an adder design, overflow is the first problem we have to consider. Let’s look at the following examples. (B = 4 bits) Example 1 Let a = -0.5 = 1.100 and b = 0.75 = 0.110. A binary addition of 1.100 and 0.110 produces 10.010. If we discard the highest bit (1 in this case), we obtain 0.010 = 0.25, which is the correct answer.
