ExtendedCalculationHandler

Description

The handler is given two variables, which it settles with the operator that is given to it.
It can also check if these variables appear more than once (var1[0], var2[0], var1[1], var2[1],…) and settles these, too.
The handler can be configured to check if the variables appear multiple times. If so, it can save the subtotals as variables or settle these with a second operator.
If no second operator was transferred, it settles the subtotals with the first operator.
The handler can be configured to round the result.

Parameter

Parameter	Default value	Description	Valid examples

Parameter	Description	Valid examples
`variable1`	First variable for performing calculations.	`var1`
`variable2`	Second variable for performing calculations.	`var2`
`index`	If the index is passed the value “true”, the handler tries to find the two variables with the pattern “var[x]” (beginning with 0) and to settle these with one another.	`true`
`operator1`	First operator used for performing calculations. Possible options: +, -, *, /, mod, potenz	`*`
`operator2`	Second operator used for performing calculations. Possible options: +, -, *, /, mod, potenz	`+`
`result`	Name of the new variable, to which the results will be written. If subtotals should be saved, these are saved using the pattern result[x].	`result`
`multiResult`	If multiResult is given with the value “true”, subtotals will be saved as process variables.	`false`
`round`	Here a number can be given, which tells how many decimal places should be kept when rounding. If nothing is entered, the numbers will not be rounded.	`2`
