ATAN Syntax ATAN(expr) Description The UniBasic ATAN function returns the trigonometric arc tangent (inverse tangent) of a numeric expression expr in degrees. With null value handling on, the result of any mathematical operation, function, or comparison involving the null value is the null value. Therefore, ATAN returns the null value when expr is the null value. Example In the following example, the program segment prints the arc tangent of the variable VAL. VAL is set to 45. VAL = 1 PRINT ATAN(VAL) Related Commands ACOS, ASIN, COS, SIN, TAN ATAN 1-109
