So if we have things like the complex number space to explore the usefulness of the square root of a -1 and then stuff like limits for being able to approximate what happens in places where a function is otherwise undefined, why do we not have something similar for treating irrationals as rations?
Is it just not a useful space to explore? Or is it something happens in one of the more advanced kinds of math that I have no knowledge of?
Just divide by a power of ten?
