Calculating the sine of single-precision real number
SIN(P)/DSIN(P)
These instructions calculate the sine of the angle specified by (s), and store the operation result in the device specified by (d).
The SIN(P) instructions can also be used as DSIN(P).
*1 The SIN instruction is not supported by the ST language and the FBD/LD language. Use SIN of the standard function.
