BBP and Bellard's formula
if what I'm hearing is correct, doesn't the existance of these two formulas make pi rational.
I don't know what the formulas are, but how can you make in irrational number rational?
This formula makes it possible to calculate the n-th digit of pi if n is smaller than or equal to 1000, without having to know the former digits. But that doesn't imply that it makes pi a rational number. A number is rational if it can be written as a fraction, N/M. There are methods to approximate pi very well as a fraction, so perhaps it is a near-rational number.
