) D : Area where calculated result is stored
Description:
1. Source designated by S can be in radians or an angle based on flag M1018.
2. When M1018= OFF, is set to radian mode. RAD=angle
×π
/180.
3. When M1018= ON, is set to angle mode. Angle range: 0

4. The TAN value of an angle specified by S is calculated and the result is stored in the register
specified by D .
S: Radian
R: Result

5. If result of D is 0, the zero flag M1020=ON.
Program Example 1:
When M1018= OFF, it is in radian mode. When X0= ON, take the TAN of RAD value (D1, D0) and
store the result in (D11, D10). The value in (D1, D0) and the result stored in (D11, D10) are all in
binary floating point format.
