I had not seen a different partial answer for this output precision question get
posted yet, so here is another method for SOME of what is wanted:
In G98 and G03 (and very likely G09 as well, but I have not tested that), you
can increase the number of printed digits for normal mode displacement
coordinates by using freq=hpmodes. I think this will give 5 instead of the
default 2 digits beyond to decimal separator.
