30. Consider a machine that rounds to 4 significant digits. Suppose initially y = 9.649 and x = 7.834. The following assignment statement, which cal- culates the expression on the right, (y + x), and then replaces the value of y on the left with the result, is in a loop that executes four times: y = y + x. After each iteration of the loop, give the value stored in y and the absolute and relative errors:
