Display star rating

I would like to show the star rating for each article on my category page grid that I am using. Is there some sort of code that I can add to the grid to visually show the star rating icons for each individual post.

I tried adding the star rating by adding the custom field, wpdiscuz_post_rating, to the grid but this just showed the star rating as a number.

I can’t find any other custom fields or shortcodes that will show the star rating.
