CubeRoot / Computation Layer

Calculate the cube root of values in a column. Similar to numpy.cbrt(), R's sign(x) * abs(x)^(1/3), or Python's x**(1/3). Returns the real cube root, including for negative numbers.

Mathematical form: $y_{i} = 3 x_{i} = x_{i}^{\frac{1}{3}}$ where:

Input domain: all real numbers
Output range: all real numbers
Property: $(y_{i})^{3} = x_{i}$

Common applications:

Volume to length calculations
3D scaling transformations
Material stress analysis
Fluid dynamics computations
Growth rate analysis
Signal processing

Note: Unlike square root, cube root is defined for negative numbers and preserves sign.

column

The numeric column for cube root calculation. Examples:

8 → 2 (2³ = 8)
-27 → -3 ((-3)³ = -27)
1000 → 10 (10³ = 1000)
0.001 → 0.1 (0.1³ = 0.001)

Works with both positive and negative numbers

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.
