How to round values in a fast formula

Hello, how are you?
I would like to round the values returned by this Fast Formula. Is there a function that does this? How can I do it?



IF l_manager_score <> 0 THEN

(

	l_mdiv = l_manager_score / l_count_comp

	l_manager_avg_score = TRUNC(l_mdiv, 2)	

	/******* Calculate the Average Rating Score 360 *******/

	IF worker_count > 0 AND pair_count > 0 AND l_self_eval_stat = 'COMP' THEN

	(

		l_manager_avg_score = l_manager_avg_score * 0.60

		l_worker_avg_score  = l_worker_avg_score  * 0.10 

		l_pair_avg_score    = (l_pair_avg_score / pair_count) * 0.30

	    L_RETURN_VALUE      = l_manager_avg_score + l_worker_avg_score + l_pair_avg_score
