Logical math operations in VCB

Hi! I suppose SU able to do some simple logical math operations in VCB. Where do I find them to learn? For example, when I’m putting needed diameter I can simply put it in VCB like 1000/2. What about other equations, do they exist? for example as in my screenshot.

No. The VCB does not support math operations. It only works for your example because it will accept fractional dimensions.
