NOTE: The reason is isn't accurate is because the formula I used was meant to be a constant (repeating the pattern over and over)so therefore, even if you typed this in a on a calculator it wouldn't give you an accurate value(unless it had an unlimited amount of memory and it had a formula to constantly edit pi. I spent about 10 minutes making this so it should have around, maybe, I don't know, 4-6 digits correctly. I personaly know pi much further but for those who do have a calculator but it doesn't have a pi function, just keep going with the pattern I have set up. Or, you could just look at this: 3.141592653589793264 (which is my limits of pi). Hope this is useful to some people).
