Is there any rational reason for calculating pi (no pun intended) to millions and millions of digits? Or is it just calculating it for the sake of calculating it?

The difference in size scale between the size of the observable universe and the size of a proton is about 10^(41).

One way to interpret this is that with 41 digits of Pi, you could construct a ring around the observable universe with the precision of a single nucleus.

So no, we probably don't need many more digits of Pi than that.
