Not to mention no one rounds stuff like that. It makes no sense. You either approximate the data going in and then if need be approximate the result again, which can give you horrible results but is useful if you are doing it in hurry or in your mind. Or you round up/down the result itself to make it easier to use. For some reason this bothers me a lot more then other bullshit coming from deranged SJW minds. I always believed math to be somehow pure.
