Mr. Mel: Great question. I was under the impression that the manufacturer had to round it to the nearest carb (e.g. .6 of a carb would be 1, 2.6 would be 3). I have seen the measurement of <1 too. Its something to watch out for though. I noticed TicTacs show 0 carbs in one tic-tac but who eats one? I bet they have about a half in each one. Let's see what the others offer. mad
