This section covers expression operators, which produce a new value based on 2 or more other values. For example, the addition operator “+” produces the sum of 2 numbers – so the top level of an element could be obtained using the + operator to add the element height to its base level:
element.height + element.level
Some operators are words, like contains which determine if one text value contains another, e.g.:
zone.name contains “Office”
The result would be true for a zone called “Supervisor Office” and false for “Utility”.
Any number of operators, values and functions can be combined in an expression.
