I would vote for a high level configuration. Very few people need less
than 0.0001", so a %.4f is fine. I know of very few machines that need
to be parametrized in millionths or less. I also know of few machines
which are also parametrized in meters or larger units.
Can you explain why you would want to print a position out in very
small fractions of a nanometer?
