Arbitrary precision - two or three approaches

[Joe Horn]

A huge THANK YOU to EdS2 for bringing the "Spigot" program to our attention. WOW, what a blast to play with! And it really tickles my toes because it's based on two of my absolute favorite things in the world: (1) Jeremy Gibbons' "Unbounded Spigot Algorithm for the Digits of Pi" (enhanced to support more inputs and functions), and (2) William Gosper's famous HAKMEM Memo 239 which gives algorithms for doing basic arithmetic on continued fractions. My heart skipped a beat when I read that description in the Spigot documentation.

If any other members here like to play with numbers like I do, and haven't given the Spigot program a try, I highly recommend it. The documentation is lengthy but well worth the time it takes to read it.

Thanks again, EdS2!
