Yeah your point is BS, because you really don't need decimals to do most things. Good for you that you can notice decimals in difference but that's not a normal thing, most weather forecast only say the integer, most air conditioners (all as far as I've seen) tell the temperature in integer, if you talk to someone else about the weather we also talk in integer.

YOU should stop pushing the idea that decimals are important into everyone else as if they are true for everyone, because they're not.
