arctan_rad(input: float64) -> float64

Computes the arc tangent of the input. The result is a float64, specified in degrees, in the range [-$\pi$/2, $\pi$/2]

Arguments

  1. input (required)
    Ratio to find the arc tangent of, float64.

Domain

This is a scalar function (calculates a single output value for a single input row).

Categories

Examples

Create a column 'arctan' with the result of the arc tangent of column 'ratio'
The resulting column will be in radians.

Given the below column ratio, arctan_rad produces the below column arctan.
