Operand 1 Operand 2
Output
(Output, flag)
Optional Optional ATN Variable
number
Data ZR
[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
 

[Example 1] ATN 100 1 Assign the inverse tangent of 1 (0.785398) to
variable 100.
[Example 2] LET 1 100
LET 101 1
ATN *1 *101
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).

(Output, flag)
Optional Optional SQR Variable
number
Data ZR
[Function] Assign the root 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.
[Example 1] SQR 1 4 Assign the root of 4 (2) to variable 1.
[Example 2] LET 1 10
LET 2 4
SQR *1 *2
Assign 10 to variable 1.
Assign 4 to variable 2.
