Title FACT 1.1 Large number factorials
Description This example program shows how to break the limitation where calculators have trouble producing factorials for large numbers. Most scientific calculators cannot handle more than 69!=1.711E98 because their displays can only handle two digit exponents. The TI-89 can handle up to 449! by default, because the display shows three digit exponents. This example program can handle up to 94851898540!

This is one of the most useful factorial programs to date. It excellently handles approximate numbers of magnitude 10*999999999996. This is a fabulous program and I definitely recommend it, though it seems that the code could be slimmed down significantly.

Overall: 9/10
