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