The inverse tangent (arc tangent) of a value, in radians.

If the value is null or NaN, it is returned unchanged.

Example

class Triangle(
    val name: String,
    val sideA: Double,
    val sideB: Double,
    val hypotenuse: Double,
    val angleA: Double,
)

collection.aggregate()
    .set {
        Triangle::angleA set atan(of(Triangle::sideB) / of(Triangle::sideA))
    }
