ATAN function
This topic describes the formula syntax and usage of the ATAN function in the Data Quality Execute Formula transform
Description
Returns the arctangent, or inverse tangent, of a number. The arctangent is the angle whose tangent is number. The returned angle is given in radians in the range -π/2 to π/2.
Tip: If you want to convert the result from radians to degrees, multiply it by
180/PI() or use the DEGREES function.Syntax
ATAN(number)The ATAN function syntax has the following arguments:
numberRequired. The tangent of an angle.
