      The number which famously has an infinite number of digits? I thought we were arguing against the real-ness of infinity.

      Also note: the method I was describing is one of the ways in which pi can be calculated.

        Instead of “has infinite digits”, I prefer to say that it CANNOT be expressed as a base10/decimal number. If you choose a different base (base-pi for example), then it very much has finite digits… :)

          It can’t be expressed in any integer-based notation without an infinite number of digits. Only when expressed in some bases which are themselves, irrational. It’s infinity either way.
