Problem 1 (2 pts): Consider a computer that uses five-decimal-digit numbers. Let fl() denote the floating-point machine number closest to r. Let r=0.5321487513, y = 0.5321304421, and z=0.532148713 x 10-5. (a): What are the values f(x), Sl(y), and (z)? (b): What is the relative error between r-y and fl(2) - Fl(y)? (c): What is the relative error between 1-2 and fl() - SI(z)? (d): What is the reason for such different errors in (b) and (c)
