"Difference" comparator in Expression Builder
I am builder some expressions in the Expression Builder.
I am using textual strings of 'true' and 'false' to do some conditional logic.
Can someone please tell me how exactly the 'Difference' Comparator works?
Most importantly, Is it the exact opposite to the 'Equals' comparator? Or in pseudo code, does it mean 'Not Equal To', or is the label on it correct, meaning 'Different To'?
No big deal but I can't find anything that explains it exactly.
