[Function] Assign the inverse tangent of the data specified in operand 2 to the variable specified in
operand 1.
The output will turn ON when the operation result becomes 0.
The setting in operand 1 must be a real variable in a range of 100 to 199, 1100 to 1199, 300
to 399 or 1300 to 1399.
The unit of inverse tangent is radian.
(Note 1) Radian = Angle x
π ÷ 180
[Example 1] ATN 100 1 Assign the inverse tangent of 1 (0.785398) to
variable 100.
[Example 2] LET 1 100 Assign 100 to variable 1.
Assign 1 to variable 101.
Assign the inverse tangent of the content of variable
101 (0.785398) to the content of variable 1 (variable
100).
LET 101 1
