It's a bit odd, yes.

But I guess it's because you can't split the first tile. If you rate, the first tile is always full. Only after that do you get to give halfsies.

The formula used here is
(rating * 2) - 1

I am not sure why, but for some reason the database saves the ratings from 0-9 (single digit), where 0 means that it is not rated, and 9 is the full 5 stars.

but is not logical if i wants to use the rating for external app/website. it is not possible to get full stars, whether i use five or ten stars rating.

if ( $rating > 0 ) $rating = $rating + 1;

You're right, I guess in most programming languages this is possible.
I guess, this will also be possible in many cases:

if ( $rating > 0 ) $rating++;

@Mithi

thanks. i think this is the only way to properly display the rating. but you need a declaration for the half stars. 

sure i can do a plus one for ten stars, but this is again not logically.

because two half points are one star. and ten half points (rating in dvdprofiler desktop app) are nine stars?

what's the problem is to add/change the number in the database.

such as for example

0 - no rating
1 - half point
2 - one point
...
9 - 4,5 points
10 - 5 points

until then i use a workaround.
