Thanks, I may be able to add truncate but I would not need to to remove normal rounding to do this. I was originally going to have all 3 modes but was having a problem with truncate and understood it is not much used. But will take a look at it again. Flooring is the same as truncate for positive numbers if I understand this correctly.
I wouldn't need to remove half decks to add exact decks. It will probably run slightly slower with exact decks. I didn't put exact decks in because I didn't think it was realistic in the casino. And the true count is then rounded anyway.
But I could understand that maybe you'd want to test exact decks on the computer to compare to other methods. Or if you had some device, or if you could use exact decks with an online game, maybe it could be realistic, dunno. Can look at adding it.
