[Nut-upsdev] zero-prepended values - why oh why?

You asked for it, so here we go. Where analog values (voltage, current,
temperature) are measured, you may have a point, although I would rather
leave this up to the driver to decide. If the UPS can't measure a value
with decimal precision, I'd prefer not to add a decimal. On the other
hand, if it can measure a value more precisely I don't see what value
there is in truncating it. Regarding integer values, I would hate to see
something like "number of batteries installed 4.0" or "outputs active
2.0". So where exact counts/numbers are involved, I think it is not a good
idea at all to add a decimal. Of course, for display purposes you can
truncate or add whatever decimal positions you like, but the drivers
should not be limited in that respect.
