Converging Series
This program uses the following series to approximate the va lue
of "e" (e
=
1/0'
+
III!
+
1/2!
+ ... +
1In!).
It then tests e ach
approximation against the value for'
' e "
generated by the calcu-
lator by pressing
OJ 11 0 .
Each approximation is displayed ,
then the difference between the approximation and
the calcu-
lator' s value for
" e" is
displayed . When the two values are equal ,
the program stops and display s the number ofterms it took for the
serie s to converge.
