The ATAN() function returns the arc-tangent (inverse tangent) of a value.

Format:  ATAN(expr)

Parameters:    expr      evaluates to a number or a numeric array.

The ATAN() function returns the arc-tangent of expr. Angles are measured in degrees.

If expr is a numeric array (a dynamic array where all elements are numeric), the ATAN() function operates on each element in turn and returns a numeric array with the same structure as expr.

Example:

ANGLE = ATAN(OPP / ADJ)

This statement finds the angle with tangent equal to the value of OPP / ADJ and assigns this to variable ANGLE.
