ATAN2(y,x)Returns the arctangent, or inverse tangent, of y/x. The result will be in radians or degrees, depending on the Angles options. ATAN2 returns a value in the range -PI to PI radians (or -180 to 180 degrees), using the signs of both parameters to determine the quadrant of the return value. This differs from the ATAN function, which always returns values in the range + PI/2. See also: |
