Tangent of an angle. Must be between –1 and +1. | |||||
The ATAN function calculates the arctangent, i.e. the angle whose tangent is specified in value. It accepts and returns numeric data.
In value, specify the tangent of the angle to return. It must be between -1 and +1.
The angle is returned in radians between -PI/2 and PI/2. To convert the result to degrees, multiply the result by 180/PI.
