While the true applications for this program (in the context it is presented in) are small, this function nevertheless does everything it is supposed to in the best way it can. One of the things that appealed to me the most is its solid error checking--meaning that your calculator will never crash and your data remains secure! Other than that, the only downside I see is the program size, but the power this program yields is worth it.
Usefulness: 6/10
