Number.Atan
The angle, in radians, whose tangent is the given number: the angle of a slope from its steepness.
Group: Number. Power Query M has it too: a query that uses it is written as in Power BI.
Syntax
Number.Atan(number as nullable number) as nullable number| Parameter | Type | Description |
|---|---|---|
number | nullable number | A tangent: the rise per unit of run. |
Returns
nullable number. An angle between -π/2 and π/2; null for null.
Examples
A slope that rises as much as it runs
Number.Atan(1)0.7853981633974483π/4, 45 degrees.
A ramp rising 1 m over 4 m, in degrees
Number.Round(Number.Atan(1 / 4) * 180 / Number.PI, 1)14
