Optional Optional TAN
Variable
number
Data ZR
[Function] Assign the 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 data in operand 2 is radian.
(Note 1) Radian = Angle x S y 180
[Example 1] TAN 100 0.785398 Assign the tangent of 0.785398 (1) to variable 100.
[Example 2] LET 1 100
LET 101 45
MULT 101 3.141592
DIV 101 180
TAN *1 *101
Assign 100 to variable 1.
45 x
S y 180 (radian)
(45 q will be converted to radian and assigned to
variable 101.)
Assign the tangent of the content of variable 101 (1)
to the content of variable 1 (variable 100).

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 S y 180
[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).
