Yeah, on second thought, it's arguable whether Avogadro's number is an
inexact integer or a non-integral approximation. The population of the
Earth is a better example. Likewise for the number of atoms in the
canonical kilogram or the number of electrons in a cubic centimeter
(which is virtually impossible to count, because of the Heisenberg's
position-velocity uncertainty relationship).
