5.6.7 Arc Tangent (ATAN)
( 1 ) Operation
The ATAN instruction calculates the arc tangent of the real number input data and stores the result in the output data.
ΠThe output data is in degrees.
( 2 ) Format
∗ C and # registers cannot be used.
( 3 ) Programming Example
In the following programming example, the arc tangent of 1.0 in the input data in MF00000 is calculated and the result
is stored in the output data in DF00000.
TAN (1.0)
-1 → DF00000 = 45.0 (degrees)
