Coordinates are absolute and f64, formatted at the shortest decimal
that reads back as the identical value. Writing the stored f32 offsets
would be smaller and would lose a quarter of a metre at four million
metres north, which is the mistake PCD made here once already and the
whole reason the core stores an f64 origin.
