As vDesigner don’t have capability to do any arithmetic operation then if I really need to do that to display something then what is the best approach of doing it?
vDesigner do have the capability to do basic arithmetic operations line SUM, DEVIDE, SUBTRACT, AVERAGE and more.
in designer 2.0:
you can do this by using copy data task and select the function you want to use and pass the data either using static or passing an variable and copy it to a variable/element.
The same can be done in Vdesinger 1 by using the copy task but you have to write functions instead of selecting it from the list. Please find the list of the functions you can use.
In vDesigner 1.0, MATH function is available for basic arithmetic operations.
Syntax is MATH[FirstValue -+*/%(Operator) SecondValue].
You can use it in Copy task same as other functions.
