Question

There are four basic phases of the algorithm for addition and subtraction:

  1. First, we need to check for zeroes
  2. Align the significands
  3. Add or subtract the significands
  4. Then, normalize the result

Show how the following floating-point additions are performed (where significands are truncated to 4 decimal digits). Explain the solution by using the phases above.

(a)5.566×10^(2 )+7.777×10^2

(b)3.344×10^1+ 8.877×10^(-2)
