Comment (by veroandreo):
Replying to [comment:12 mmetz]:
> I have uploaded a patch (v_vect_stats_unique_cats_no_half.diff) that
correctly removes duplicate cats (similar to
v_vect_stats_unique_cats.2.diff) and additionally eliminates the usage of
half (adding 0.5 to the result). This half makes only sense if the result
is to be converted to integer and if the result is a positive number. The
result is always floating point, therefore adding 0.5 causes wrong
results.
Thanks Markus! I applied the patch and tested with Moritz's test data and
examples, and also with my own data. Counts are fine and also stats :)
