Nine decimal places seems excessive.

We can apply some rudimentary validation: no latitude or longitude
values greater than 360, for instance (perhaps other criteria
dependent on the coordinate system); latitude and longitude should
have the same number of decimal places; trailing zeroes are
significant and must not be discarded.
