Sure. Think of two points, and draw a line between them.

One way to distinguish these is points "in" a line and
points "on" a line, when the line is just "going" or
"drawing" the line, line-drawing, "in" the line, instead
of being range, found, picked, or bounded, "on" the line,
then there's also a third definition of continuity,
definition of gaplessness, "about" or "around", the
line, that gets into the formalism of Fourier and
is quite a bit later than the Aristotlean, since when
at least two definitions of continuity that aren't the
same exist, and since Fourier-style, since when a third
was established by Fejer and Dirichlet to be around,
then that these days there's Jordan _measure_ again,
where for a while it had to be content being "content",
and Dirac's delta is a _function_ again, when for a while
it had to be content being a distribution or functional,
that "remedial line-drawing" is a thing again, as for example
the necessity that Hilbert found of a postulate of continuity,
for geometry.

So, "line-reals", "field-reals", and "signal-reals", are
three _different_ definitions of completeness as gaplessness,
in the _repleteness_, of definition, _required_ due their
recognition, for conscientious formalists.
