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

Calculating the cosine of single-precision real number

COS(P)/DCOS(P)
These instructions calculate the cosine of the angle specified by (s), and store the operation result in the device specified by
(d).
The COS(P) instructions can also be used as DCOS(P).
