Kevin,

You were perhaps sneaking up on the idea of a continuous system. Definition
2 below.

Continuous:

1 : marked by uninterrupted extension in space, time, or sequence

2 of a function : having the property that the absolute value of the
numerical difference between the value at a given point and the value at any
point in a neighborhood of the given point can be made as close to zero as
desired by choosing the neighborhood small enough
