Converging Series
This program uses the following series to approximate the value
of “e¢” (e = 1/0' + 1/1' + 1/2! + . . . + 1/n!). It then tests each
approximation against the value for “‘¢’’ generated by the calcu-
lator by pressing [El .Each approximation is displayed,
then the difference between the approximation and the calcu-
lator’s value for “‘¢”’ is displayed. When the two values are equal,
the program stops and displays the number of terms it took for the
series to converge.
