 SIN values between -1.0 to 1.0 can be designated by (S).
 The angle (operation result) stored at (D) is stored in radian units. For conversion between degrees and radian values, refer
to the RADD and DEGD instructions.
 When the operation results in "-0" or an underflow occurs, the operation result is processed as "0".
 When setting input values from programming tools, rounding errors may occur.
For precautions when setting input values from programming tools, refer to "6.3.4 Single/Double-Precision Real Number
Data".
