rounding up to nearest (5) days

[ReluctantProgrammer]

I have a field that shows the total # of actual days and I want to create a field that will take that # and round it up to the nearest 5 days.  

Example 1:  total actual working days = 18; total days = 20

Example 2:  total actual working days = 24; total days = 25

How can I do that?  Here is my file.

@ReluctantProgrammer :

You can use below JS method to get it done.

Math.ceil(total actual working days / 5) * 5;

E.g:

Math.ceil(18 / 5) * 5;
20

That's what I needed.  Thanks!!
