return acos(0.5) * 180 / pi() as degree
Result:
| degree |
|---|
| 60 |
asin()
Computes the angle in radians whose sine is a given number, the output radians will be in the range [-𝜋/2, 𝜋/2]. If you need the result in degrees, which is in the range [-90º, 90º], you can convert it using the degrees() function.

return asin(0.5) * 180 / pi() as degree
Result:
| degree |
|---|
| 30 |
atan()
Computes the angle in radians whose tangent is a given number, the output radians will be in the range [-𝜋/2, 𝜋/2]. If you need the result in degrees, which is in the range [-90º, 90º], you can convert it using the degrees() function.
