found bug in post rating

I found a bug in the post ratings. When I set a criteria score to 4.5 it would display as 3.5. After taking a look at the post-rating.php file I found the problem. Its in the block at line 251 which is listed below.

<?php
if($rating_1 != "0" && $rating_1 == "4.5" && $rating_1_text != "" ){
?>
<li><?php echo  esc_attr($rating_1_text); ?>
	<span class="score" style="color: <?php echo esc_attr($cat_data["catBG"]); ?>">
		<i class="fa fa-star"></i>
		<i class="fa fa-star"></i>
		<i class="fa fa-star"></i>
		<i class="fa fa-star-half-o"></i>
		<i class="fa fa-star-o"></i>
	</span>
</li>
<?php } ?>

The block should read

<?php
if($rating_1 != "0" && $rating_1 == "4.5" && $rating_1_text != "" ){
?>
<li><?php echo  esc_attr($rating_1_text); ?>
	<span class="score" style="color: <?php echo esc_attr($cat_data["catBG"]); ?>">
		<i class="fa fa-star"></i>
		<i class="fa fa-star"></i>
		<i class="fa fa-star"></i>
		<i class="fa fa-star"></i>
		<i class="fa fa-star-half-o"></i>
		
	</span>
</li>
<?php } ?>
