Question

>=epsilon and ans <= x does that mean >=epsilon and ans <= x Or >=epsilon and ans epsilon and ans <= x

Generally speaking, elsilon, $\epsilon$, is a range of accuracy.  So when you are within $\epsilon$ then your result, traditionally delta or $\delta$, is good enough to be an answer.

This $\epsilon$ to $\delta$ relationship comes from math.  It is a part of explaining a concept in calculus.  Because many computer scientists have come from math backgrounds, especially the early ones, there are several mathematical terms used to explain computer concepts.

In this case, you are trying things out to see if they are the answer.  You get closer and closer each try.  You might be a little high or a little low, but you are getting close.  In mathematical terms, once you are within $\epsilon$ closeness, you declare that you have an answer that is acceptable because it is within $\delta$ of the true answer.

I hope that helps explain the goal and process of this sort of approximation.
