Support for floating numbers in rating.

[mirxaibbi]

Hi,
I'm using this star rating in my project. So far it's looking really good except one thing. The requirement that I'm working on needs to fill stars based on average rating. Is there any way to fill up the stars based on average rating like if the rating is 2.8, it has to fill 2 stars and 80 percent portion of third star. I've reviewed the documentation but I only found the way to fill up half stars.
If there's any way than can help me in this regards. I would really appreciate that.
Thanks.
