Operands:
S: Source device (0°≦S<360°) D: Operation result
Explanations:
1. TAN instruction performs tangent operation on S and stores the result in D.
2. The value in S can be set as radian or degree by flag M1018.
3. M1018 = OFF, radian mode. RAD = degree ×π/180.
4. M1018 = ON, degree mode. Degree range: 0°≦degree<360°.
5. Flag: M1018 (Flag for Radian/Degree)
6. See the figure below for the relation between the radian and the operation result

7. If operation result in D is 0, Zero flag M1020 = ON.
