Description Computes the trigonometric arc-tangent of the input value. This function also deals with data from -pi/2 to pi/2 and fails when the arc-tangent function becomes undefined. Consequently atan2 only deals with data 0 to 2pi and will not fail when the arc-tangent function becomes undefined.
Arguments and Return Values Parameters: An array of any numeric data type or organization containing the tangent values of angles in radians. Return Value: An array of identical type and organization of the input containing the arctan of the input
Usage Syntax: atan(object = VAL)
