Function need to evaluate the expression

your options are pretty much to either manually build a parser (if you control the allowed operators tightly enough, it's doable, but cumbersome as stefan already mentioned), or use undocumented functionality like "function-which-must-not-be-named".

There is no such function in Appian. And parsing this manually becomes a pain quickly as you need to evaluate the operations in the right order.

Hey Mathieu Drouin

Thanks for your response.

This will only work for sum of numbers but what I need is to calculate the whole expression which includes mathematical operations like +,-,/,*
Example... If user enters 5*2+1-10/2 then the result should be 6.

a!localVariables(
  local!text: "1+2+3+4+5",
  local!textItems: split(local!text, "+"),
  local!textItemsInteger: tointeger(local!textItems),
  sum(local!textItemsInteger)
)

Yeah, you could do that. But I don't know, seems a little brittle. Seems like something that may be better suited for an LLM.
