ATAN is a DAX function that returns the arctangent, or inverse tangent, of a number, providing the angle in radians between -p/2 and p/2.

Syntax

ATAN( Number )

Argument	Properties	Description
Number		The tangent of the angle you want.

Return Values

Returns the inverse hyperbolic tangent of a number.

Remarks

To express the arctangent in degrees, multiply the result by 180/PI( ) or use the DEGREES function.
