Hi.

I have read up on a number of ways to have an app calculate pi, but I keep coming back to the same hard limit. Pretty much every app I know of in Windows stops adding decimal places after about 10.

If I wanted to calculate Pi to 1000 decimal places, the algorithm is just going to round to the nearest billionth (or whatever). What am I missing?

How are computers getting pi into the trillions of digits?
