Half stars in fivestar

Hello everyone,

I installed fivestar on my website and it is working wonder. I use it to rate books or movies in my reviews.

However, I would like to know if there is a way to enable "half star" rating (or "half fire" in my case).
For instance, I would like to give a book a 4.5 rating, so "4 fires and a half".

I'm asking this because I have seen this feature is enabled with averages of user votes.

And please don't tell me that I should just use a 10-star rating ;-)

Thanks !
