Many physical theories characterize their observables with unlimited precision. Non-fundamental theories do so needlessly: they are more precise than they need to be to capture the matter of fact about their observables. A natural expectation is that a truly fundamental theory would require unlimited precision in order to exhaustively capture all of the physical matters of fact. In this talk I will argue against this expectation and I will advocate that there could be a fundamental theory with limited precision. I will make my case for this claim by considering a collection of results from perturbative quantum field theory.
