Addendum:

The issue seems to surface if the arithmetic takes place in a loop, when you do the subtraction (or addition as well?) multiple times.

I don't seem to get this problem when the subtraction happens only once in a subroutine (not in a loop).

    Have you run the code in my reply? There's no loop involved. Also, have you clicked the link provided there and read the article? It answers your question about adition clearly.

      Yes, I ran your code, and then modified mine based on it after that.

      Hmm...I am still puzzled why I haven't seen that kind of anomaly in other parts of my code that do this sort of arithmetic even though I have been testing it for weeks now.
