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