Hello,

Is it possible use the absolute value function in survey123? I need to formulate a logic statement based on the weight difference of two things. Example: "If the difference is > 0.3, the test fails." I have not seen any examples online showing absolute value. Any solutions or work arounds you know of would be greatly appreciated.

Thank you!

In the absence of the abs() function, will the above work for you?

You could keep the Calcu question as a 'calculate' and then use that variable in other expressions.
