===== Operators =====

Standard operators can be used in all formulas, such as +, -, *, /, <, >, <=, >= ( and ).  IIF is possibler for expressions: <, <=, >, >=

===== Conditionals ===== 

In order to test for a condition, you can use the syntax:
''VALUE('variable',0) > 5 ? 1 : 0''
The comparison uses the IIF syntax -  so if compared value > 5 the output would be 1 and otherwise (:) 0.

===== Examples =====
This would add the two Watt values of two inverters together and convert to kWh:

''VALUE('delta0w_ac') / 1000 + VALUE('delta1w_ac') / 1000''

This example will output 'High' or 'Low' based on the threshold value.

''VALUE('myvar')>5?'High':'Low' ''
