What I want seems pretty simple, but I've spent hours now trying different ways - using part equations, custom properties,and BOM table equations - to no avail. 
I want to show the MIN and MAX limits of a dimension in a BOM table.

I want to show this in the format "MIN / MAX" with 4 decimal places of precision. 
Solidworks however, seems to ignore precision on anything in the second half of the concatenated numbers.

I’ve specified 4 decimal place precision, tried that a couple ways even, but Solidworks 2016 SP1 just seems to ignore the precision specified and gives me three decimal places for the second argument. 

Looking for any suggestions on how to accomplish this.
