gn:act_calculate

Description

Action used to perform calculation operations on different actors and stores result in target.

If calculations with trigonometric functions give the wrong results, please note that the trigonometric variables input is expressed in radians, not degrees

By default, the format of calculation result on GnEditText is set to 0.00.

If the result needs to be formatted differently, check attribute gn:s_decimalFormat on GnEditText

Action signatures

Calculate result into target widget

[gn:act_calculate]|[target,calculationFormula]

Parameter	Description
target	target from where the while action is using value as expression parameter Valid targets: widgets: GnEditText variables: number dateTime date
calculationFormula	represents formula to be calculated WidgetId’s, String resources or ginstr app variables can be used to replace variable placeholders in the equation, i.e. 3*sin(@+id/widgetId)-2(@+variable/varId-2). All values in actors should be numeric or they will be ignored in calculation Actors that can be used as calculation variables: widgets: GnEditText GnDatePicker GnDateTimePicker variables: number dateTime date string resources

Example

Calculate with operand

@variable/myResultVar - target where the calculation result will be stored

@+id/widgetOne*@variable/calcVarOne - calculation formula

⤷ [gn:act_calculate]|[@variable/myResultVar,@+id/widgetOne*@variable/calcVarOne]

Calculate with function

@variable/tour_scheduledTourStartMinutesNumber - target where the calculation result will be stored

floor((@variable/tour_scheduledTourStartDecimal%1)*60) - calculation formula with floor function

⤷ [gn:act_calculate]|[@variable/tour_scheduledTourStartMinutesNumber,floor((@variable/tour_scheduledTourStartDecimal%1)*60)]
