The Function Block TAN calculates the tangent.
Note: The Function Block uses radians. See Function Block DEG2RAD and RAD2DEG.
An input value is expected to be a number. The Function Block attempts to convert the value of a string into a number. The boolean value TRUE is converted to a 1.
Note: Also see the article String Conversion To Numbers, if you are working with strings.
The output returns the tangent as an integer. In case of error, the value NAN (Not a Number) is returned.
