Calculating The Arc Cosine Of Single-Precision Real Number - Mitsubishi Electric MELSEC iQ-F FX5 Programming Manual

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).
