I read that paragraph as describing generally what the precision
means, with the table below detailing more specifically how it is
used. I think for 'g' this is just trying to contrast it with 'f'
where it really is just the number of digits displayed after the
decimal point. The table entry for 'g' on the other hand quite clearly
says, "for a given precision p >= 1, this rounds the number to p
significant digits".
