Operands:
S : Specified RAD value or an angle (0

) D : Result of the SIN operation
Description:
1. Source S can be in radians or an angle based on flag M1018.
2. When M1018= OFF, it is set to radian mode. RAD=angle
×π
/180.
3. When M1018= ON, it is set to angle mode. Angle range: 0

.
4. The SIN value of an angle specified by S is calculated and the result is stored in the register
specified by D .
5. Flag: M1018 flag for radian/angle.
S: Radian
R: Result

Following shows the relation between radian and result:
6. If result of D is 0, the Zero flag M1020=ON.
Program Example 1:
When M1018= OFF, the radian mode is used. When X0= ON, the SIN of the RAD value (D1, D0) is
calculated and the result is stored in (D11, D10). The result in (D11, D10) is in binary floating point
format.
