The ACOS function returns the arccosine of a number, that is, it returns the arc whose cosine is the indicated one.
Syntax
ACOS(
<value>
)
Parameters
- value: Cosine of the arc to be obtained. It should take a value between -1 and 1 (both values included).
Returned value
The ACOS function returns a real number representing an angle in radians in the range 0 to PI.
Additional Information
The result is a value in radians. If you want to express it in sexagesimal degrees, you must multiply it by 180/PI() or use the DEGREES function. If the arccosine of a number outside the range [-1, 1] is requested, the ACOS function returns an error.
Examples
In this example, we create a calculated column containing the arccosine of the angle contained in the Cos column using the following DAX expression:
ACos = ACOS(data[Cos])
