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

 

 

Format

 

ATAN(expr)

 

where

 

exprevaluates 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.
