That one is conceptually similar, but doesn't use logs (so p^n could quickly underflow if n is very large). Also, it only does a lower tail, rather than a cumulative range between any two min and max values. So it's quicker to type in, and probably runs a little faster, but it's a bit more limited. Use mine if you need to do an extremely large number of trials. It'll take a good amount of time to run, but it's still faster than submitting your job to the computing center and picking up the results in the morning, right?

That PPC Journal HP 25 Library is a real treasure trove. The prime factor finder (#33, I think it was) is extremely clever and efficient, even without enough memory/features to do a full mod 30 sieve.
