Every now and again I get questions about how to "round" numbers in workbook in QTO. Well there is no overall setting but you can tell the formula box that you want the workbook to "round" specific fields.
To round your numbers, click in field you want you round so it will display in the formula box.
Now add the text "round" after the =. You will need brackets too in order to tell QTO what to "round"
To round for assemblies or thing that already contain brackets, simply just add the round after the = and it will "round" everything already in your formula.
Check out the above image and notice that all the fields are "rounded" to whole numbers. This could be another great thing that you build into your catalog.
Hope this helps to answer a few questions.
