In this case, 0.4 nm. Or 2.5 aluminium atoms.

Andy,
I haven't calculated how far the midpoint of the arc is from the midpoint
of a straight line from point to point using the values in your example but
I know it would not be much.
I do know APT uses 2500 inches as the cutoff point for radius calculation.
I don't know the exact reason for
LinuxCNC G-code assumes that the programmer wanted a full circle if
the coordinates of the start and end points in the plane are "the
same".
Currently both the preview interpreter and motion use the angle
between the start and end points of an arc to decide if the start and
end coordinates are
