ATAN Returns inverse tangent.
expression A numeric constant, variable, or expression for the value of the tangent.

The ATAN procedure returns the inverse tangent. The inverse of a tangent is the angle that produces the tangent. The return value is the angle in radians. p is a constant which represents the ratio of the circumference and radius of a circle. There are 2p radians (or 360 degrees) in a circle.

Return Data Type REAL

Example:

PI        EQUATE(3.1415926535898)     !The value of PI

Rad2Deg   EQUATE(57.295779513082)     !Number of degrees in a radian

Deg2Rad   EQUATE(0.0174532925199)     !Number of radians in a degree

CODE

InvTangent = ATAN(TangentAngle)      !Get the Arctangent
