When using iProperty names in a custom iProperty, it is not possible to apply mathematical functions.
For example, the basic unit cm can not be changed in mm. Even functions like round() are not possible.
The reason for this is probably that basically a text field is generated.
The Problem was earlier described in this blog article
It would be very useful if this possibility were created, as at the moment this functionality can only be created by using an iLogic rule or other programming.
