What will the Action return if the input parameter N for sqrt is negative?

When you input a negative number into the square root function (sqrt) in most programming contexts, including OutSystems, the function will not be able to compute a real number result. Instead of returning a valid number or a real-valued result, it will generate an error or an exception, indicating that the operation cannot be completed as expected.

This behavior arises from the mathematical properties of square roots; the square root of a negative number does not exist within the set of real numbers, leading to the conclusion that attempting to compute it results in an error. Therefore, when the input parameter N for the sqrt action is negative, the function returns an error message to signal that a valid operation could not be performed.
