The point p is within distance d <within a distance d> of X.
Then F is within d of the integers.
The zeros of L-functions are all accurate to within 10-5.
Note that f is determined only to within a set of measure zero.
Each component that meets X lies entirely within X.
Within I, the function f varies by less than 1.
This example falls within the scope of Cox's theorem.
