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).
*1 The COS instruction is not supported by the ST language. Use COS of the standard function.
