Sure its neat to have hundreds of digits for some esoteric project, but what is the goal. Give an example of the usage of this tool suite. Is it to prove a theorem? Is it to design a new compression algorithm? Is it to simulate a fluid flow problem? What is the goal?

In my line of work, 3 significant digits is ALL we can ever hope for. With 4, we would be virtually guaranteed contract renewal for the next 5 years. But 100s of digits? C'mon.

Please explain WHY calculating 100 factorial to the final place is of any utility.

BTW, mathematica, maple and other symbolic programs have been able to do this for years.
