Problem 2: Let p, = 1+23". 1. Find out the floating-point form of p2 using five-digit rounding. 2. It turns out that there exists N e N+, such that the 64-bit binary machine representation of equal to the exact value of pn for n = 1,2, . , N, but not for N + 1. Find out this N. is Pn ... 3. What is the numerical value of the 64-bit representation of pn when n > N? Explain your
