ArcTan / Computation Layer

Calculate the inverse tangent (arctan) of values in a column. Similar to pandas arctan(), numpy.arctan(), or R's atan() function. Returns angles in radians.

Mathematical form: $y_{i} = arctan (x_{i}) = tan^{- 1} (x_{i})$ where:

Input domain: all real numbers
Output range: $y_{i} \in [- \frac{π}{2}, \frac{π}{2}]$

Common applications:

Slope-to-angle conversion
Phase calculation in signals
Robot arm positioning
Camera view angles
Trajectory analysis
Coordinate transformations

Note: Always returns values between -π/2 and π/2 radians. For full circle angles, consider using arctan2 with x,y coordinates.

column

The numeric column for inverse tangent calculation. Examples:

Slopes (1.0 → 0.785... rad ≈ 45°)
Ratios (0.577 → 0.524... rad ≈ 30°)
Large values (1000 → 1.570... rad ≈ 90°)
Zero (0.0 → 0 rad = 0°)

Accepts any real number input

Name for the new column. If not provided, the system generates a unique name. If AsColumn matches an existing column, the existing column is replaced. The name should follow valid column naming conventions.
