write_dump, greater numerical precision on coord. and velocities

To LAMMPS users,

I had previously asked about the ability to write single dump files at only a couple "random" times throughout an MD simulation.

This was made possible through the write_dump command, which is not officially part of the LAMMPS source code.

However, I would like greater precision on the coordinates and velocities; it would be nice to be able to specify this as part of the dump command as well.

Would someone be able to help me implement this in the write_dump command, if it is possible?
