Hi;

None that I know of, the BBP is for hexadecimal digits.

Hi bobbym

Is there a way of getting the nth decimal digit of pi by a spigot algorithm?

Hi;

Here is an example of a spigot algorithm being used to get the 50 th digit from ln(2). Process is the same for pi.

To see how pi is done check out the BBP formula right here.

Hi;

Yes, it is called a spigot algorithm. It can zero in on the nth digit without having to get all the preceding ones

I've heard that there is a function that gives nth digit of pi,is it true?if it is i'd like to know more about it.
