Problem with hover and half star

There is a bug when half option is true. When user hovers the second half of the star (for the example fifth star) and clicks, if the rating is > 4.5 user will see rating of 4 which is not correct, it must be 5, because the two halves of fifth star are hovered and user suggests that this is rating of 5. I tried with round option, but even if I do this:
round : { down: .1, up: .51 },
the bug still exists if the clicked score is 4.5703125, user needs to click minimum 4.6, which is not correct. If star or half star is hovered, then on click this must be the rating.
