The function block SUB subtracts the further inputs from the 1st input.
Note: This function block can have more than two inputs. You can right-click on the function block to add another input.
The inputs expect values with numbers. The value of a string is attempted to be converted into a number. The boolean value TRUE is converted into a 1.
Note: Also see the article String Conversion To Numbers, if you want to work with strings.
The output returns the difference of all inputs as an integer or floating-point number.
