A function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances. - Sets the unit for angles in all trigonometric functions.
Inputs
IN : BOOL If TRUE, turn all trigonometric functions to use degrees
If FALSE, turn all trigonometric functions to use radians (default)
Outputs
Q : BOOL TRUE if functions use degrees before the call
Remarks
This function sets the working unit for the following functions:
| SIN COS TAN ASIN ACOS ATAN ATAN2 |
sine cosine tangent arc-sine arc-cosine arc-tangent arc-tangent of Y / X |
