The ATAN function returns the inverse tangent. The specification for the ATAN function is:


FUNCTION ATAN (n NUMBER) RETURN NUMBER;


where the number n must be between −infinity and infinity, and the value returned by ATAN is between −pi/2and pi/2.

The Atan function is a Number Request that calculates the value (in radians) of the angle whose tangent equals a specified number.
The arctangent function is the inverse function of the tangent function and calculates the angle for a given tangent x.

The Atan function is a Number Request that calculates the value (in radians) of the angle whose tangent equals a specified number (the inverse of the Tan function). In the diagram below, the arc tangent of b/a is X. The units of X are radians. Arc tangent is sometimes written tan-1.
