Yet that is still a rounding thing.Limits are used in all the higher branches of mathematics to do calculations like these that don't make sense. They are taken as fact because a number infinitely close to a that approaches a is...a
Bold = repeating
For example. .9 is a number infinitely close to 1. However, let me prove to you it is 1
x = .9
10x = 9.9
10x - x = 9.9 - x
9x = 9.9 - .9
9x = 9
x = 1
Similar happens with 1/3 = 0.3333333333333333 * 3 = 1
