Have a look at the function value_list_to_string() in src/cvs.c. The
output is formatted in the if-cascade that checks 'ds->ds[i].type'.
Currently, it uses the default precision.

Currently, this is not configurable at runtime but it's hard-coded in
the plugin. However, I think it might make sense to let the user specify
the format string that is to be used for printing floating-point values
(it should be noted, though, that this let's the user introduce rather
nasty mis-configurations). Do you want to give that a try?

Cheers,
Sebastian
