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

S: Radian
R: Result (TAN value)
7.
If operation result in D is 0, Zero flag M1020 = ON.
Program Example 1:
M1018 = OFF, radian mode. When X0 = ON, DTAN instruction performs tangent operation on the
radian value in (D1, D0) and stores the TAN value in (D11, D10) in binary floating format.
