Hello Luq,

I think it can be done without too much work... A few subroutines to do the Arc* formulas. In Calculus, you can use Series on the Arc* rountines. PBP does do floating calculations.

The only problem you may have, is the Accuracy. If you want just a rough idea, that is fine...If you want to have exact, or close to exact, you will not achieve this. Especially since Dividing in PBP will leave you (at most) a 16 bit number that is usuable. And when you Multilply and Divide so many times, that 16 bit number becomes a rather rough number.
