(1) float and double variable can be represented by the smallest positive number is how much? (2) analysis of the code in enough time if run to completion, if you can give n_f, and n_d value. (3), respectively, with a variable of type float and double type to save part and Sk recursive calculation (1) (seen in the experimental value-seven job file), and to determine whether the result of convergence? Reasons? Theoretical analysis and programming test, given the convergence, when the value of n. (4) design summation algorithm, using a float variable, makes convergence n as large as possible, part as accurately as possible and Sk
