Operands:
S: Source device (binary floating value) D: Operation result
Explanations:
1. ATAN instruction performs arc tangent operation on S and stores the result in D
2. ATAN value=TAN
-1
3. See the figure below for the relation between the input and the result:
R
S
2
2
-
0
S: Input (TAN value)
R: Result (ATAN value)
4. If operation result in D is 0, Zero flag M1020 = ON.
Program Example:
When X0 = ON, DATAN instruction performs arc tangent operation on the binary floating value in
(D1, D0) and stores the ATAN value in (D11, D10) in binary floating format.
