Here is my formula.
If([Duration (Manual)]<>Minutes(0),[Duration (Manual)],[Time out]-[Time In])
I need it to round to the nearest .25 hour. For example if it is 4.667 i want it to round to 4.75. If it is 10.15 i want it to round to 10.25. If it is 7.99 i want it to round to 8.0. How would I do this?
