**Takes the arc tangent of a number and stores the result (in radians) in the destination .**

#### Example

Equation: F8:5 = ATAN (0.3)

#### Ladder Logic Solution:

#### Note

- If an overflow is generated or an invalid source is detected, a minor error will be generated. This error should be cleared to avoid a major error.

Equation: F8:15: = TAN (10)

#### Ladder Logic Solution:

#### Note

- If an overflow is generated or an invalid source is detected, a minor error will be generated. This error should be cleared to avoid a major error.
