Calculus make use of the fundamental notions of convergence of infinite sequences and infinite series to a well-defined limit.

What you are calling an exact result is only a limit function. All “things” will measure infinitely.

Still not understanding what your issue is with calculus. I think so far you only have a problem with its outcomes when you feed it garbage. We expect to see "Calculus" diverge when integrating near the lattice spacing. I don't think we wholly disagree but I am doubtful you are going to make headway fighting against calculus.

[FollowingTheDao]

I don’t have a problem with calculus, I’m just expressing its limitations. Using calculus to know the area of a circle is useful but it never really measures the area of a circle because the area of any circle is infinite.
