Have you tried using the Round(,) or RoundTo (,,) in the Formula calculations? You may get a more accurate count that way. 

I haven't tried that.  Can you elaborate a little?

When used in a Formula Calculation, those Functions in the Create Formula module allow us to set the rounding on the Item and to the nearest XX. I suggest you read up on Round and Roundto, then practice until you consistently get the desired result. Sometimes Labor and Material have to be in standalone Items for us to get the exact results we are looking for.

Thank you for your time responding to my question.

Thank you for your timely response, but I'm not looking to round item quantities.

What I'm trying to accomplish is to round the Labor, Equipment and Material within the item to whole units, for example if the labor for a particular activity is calculated as 4 m-h, I would want to go to full day so in effect, rounding the labor to the next 8 m-h.  Or in the case of concrete, I would want the material to be round up to each 10 CY (average delivery truck size).

I expected the rounding tab on the database item entry form would do that,  but it looks it does not.

Okay. I will show you an example of materials rounded UP to the next full box. This will work for your concrete. (the Item's Unit of Measure will need to be CY, and your deviser will need to match). I have not set up something for labor, but I can't imagine it not working. Note that the labor and material will need to be on separate Items.

This is the Calculation inside the Assemble. 

 IF( qProvide Material? , cCove Base Material Calc ,0) the  cCove Base Material Calc - is a nested Formula.

It looks like this:  ROUNDTO( afHow Many Linear Ft /120,1,1)  The How Many Linear Ft is a Formula allowing the user to input the needed LF. The cove base comes in boxes of 120 LF. So, If 90' are needed - One box will be priced. If 121' are needed, 2 boxes will be priced. If 2,000' are needed, 17 boxes will be priced, etc.
