'minRating' => 1,
		'maxRating' => 5,
		'value' => 0,
		'ratingStepSize' => 0.5,
		'starCount' => 4,

produce 4.5 stars

'minRating' => 1,
		'maxRating' => 5,
		'value' => 0,
		'ratingStepSize' => 0.5,

produce 9 stars

this is the source of the problem

protected function renderStars($id,$name)
	{
		$inputCount=(int)(($this->maxRating-$this->minRating)/$this->ratingStepSize+1);
		$starSplit=(int)($inputCount/$this->starCount);
		if($this->hasModel())
		{
			$attr=$this->attribute;
			CHtml::resolveName($this->model,$attr);
			$selection=$this->model->$attr;
		}
		else
			$selection=$this->value;
		$options=$starSplit>1 ? array('class'=>"{split:{$starSplit}}") : array();
		for($value=$this->minRating, $i=0;$i<$inputCount; ++$i, $value+=$this->ratingStepSize)
		{
			$options['id']=$id.'_'.$i;
			$options['value']=$value;
			if(isset($this->titles[$value]))
				$options['title']=$this->titles[$value];
			else
				unset($options['title']);
			echo CHtml::radioButton($name,!strcmp($value,$selection),$options) . "\n";
		}
	}

I think the (int) casting does something bad to the rating... trying to figure it what exactly...

It seems like it ment to work only with integers...
But half rating is normal actually...

To make it show 5 stars with step 0.5 you should set

'minRating' => 0.5,
		'maxRating' => 5,
		'ratingStepSize' => 0.5,
		'starCount' => 5,

But in spite of that, starCount just not work as it should


Another issue I noticed

'minRating' => 0.5,
		'maxRating' => 5,
		'value' => 0.75,
		'ratingStepSize' => 0.5,
		'starCount' => 5,

will show nothing...

So to make it show something you should round to closest half... or ceil floor...
