Does Pick's formula hold for non-integer lattices (nodes with non-integer coordinates)?

I heard that it holds for any lattice (given lattice is: we take two groups of parallel lines and intersect them - so we have a lattice based by a fundamental parallelogramm) - nodes of such lattice need not be integer numbers. The formula is the same but if it gives number 7 it means "7 times the area of a fundamental parallelogramm of that lattice"

    $\begingroup$ Seems reasonable. You could take a proof of Pick for the usual lattice, and see whether it goes through for the general lattice. Earlier related question: math.stackexchange.com/questions/768/… $\endgroup$ – Gerry Myerson Apr 16 '19 at 10:21
  • $\begingroup$ I think the general lattice is done in arxiv.org/abs/1707.04808 although all the diagrams are for the square lattice. Why not have a look, and report back? $\endgroup$ – Gerry Myerson Apr 16 '19 at 10:33

  • $\begingroup$ @Gerry Myerson It didn't clarify anything for me. $\endgroup$ – Code Complete Apr 20 '19 at 15:23
  • $\begingroup$ Sorry to hear that. I'll try to have another look, though it won't be for a couple of days. $\endgroup$ – Gerry Myerson Apr 20 '19 at 22:19
