=======ExtendedCalculationHandler=======
==== Description ====
The [[en:software:tim:actionhandler:|handler]] is given two [[en:glossar#process_variable|variables]], which it settles with the operator that is given to it.\\
It can also check if these [[en:glossar#process_variable|variables]] appear more than once (var1[0], var2[0], var1[1], var2[1],...) and settles these, too.\\
The [[en:software:tim:actionhandler:|handler]] can be configured check if the [[en:glossar#process_variable|variables]] appear multiple times; if so, it can save the sub-totals as [[en:glossar#process_variable|variables]]\\  or settle these with a second operator\\ 
If no second operator was transferred, it settles the sub-totals with the first operator. \\ 
The [[software:tim:actionhandler:|handler]] can be configured to round the results.

==== Parameter ==== 
== variable1 ==
First variable for performing calculations (see [[#example]])

\\ == variable2 ==
Second variable for performing calculations (see [[#example]])

\\ == index ==
If 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. (see [[#example]])

\\ == operator1 ==
First operator used for performing calculations.  Possible options: +, -, *, /, mod(Modulo), poten. (see [[#example]])

\\ == operator2 ==
Second operator used for performing calculations.  Possible options: +, -, *, /, mod(Modulo), poten. (see [[#example]])

\\ == result ==
Name of the new variable, to which the results will be written. If sub-totals should be saved, these are saved using the pattern result[x].  (see [[#example]])

\\ == multiResult ==
If multiResult is given with the value "true", sub-totals will be saved as process variables. (see [[#example]])

\\ == 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. (see [[#example]])
