The division algorithm states that for any integer, a, and any positive integer, b, there exists unique integers q and r such that a = bq + r (where r is greater than or equal to 0 and less than b). List the steps of division algorithm 7. hardware – we do not cover computer architecture or the design of computer hardware since good books are already available on these topics. First, we need to align the exponent and then, we can add significand. Most popular in Computer Organization & Architecture, More related articles in Computer Organization & Architecture, We use cookies to ensure you have the best browsing experience on our website. Now adding significand, 0.05 + 1.1 = 1.15 So, finally we get (1.1 * 10 3 + 50) = 1.15 * 10 3. After aligning exponent, we get 50 = 0.05 * 103, Now adding significand, 0.05 + 1.1 = 1.15, So, finally we get (1.1 * 103 + 50) = 1.15 * 103.
