I haven't yet decided if we strongly disagree, or we agree on a level deeper than I can fathom.

    There is no exact value for Pi.
Would you say the same of the square root of two, or one-seventh, or thirteen?

Regardless, I conclude that you deny the following statement:

For every real number q, it must be the case that q < pi, or q = pi, or q > pi.

I conclude that, if I describe two circles that each have a radius of 1, you will not know if they have the same area.

I guess I should clarify, that in the language of mathematics pi can be said to have an exact value. However, it cannot be realized in a physical sense, that is, printed as an exact value in decimal form.

Math can have absolute axioms, but the physical world has only approximations.
