Sum of four separate time columns

Hello!

I am trying to calculate the amount of time worked (hours and minutes). The formula needs to take the difference between two times and the difference between another 2 times and then give the sum of both times in hours and minutes.

I am using HOURS_DIFF({Break},{Clocked In})+HOURS_DIFF({Clocked Out},{Break End}) to try and achieve this, it is close but rounds up to the closest hour. How do I get this accurate to hours and minutes?
