Atn
Returns the arctangent of a number
result = Atn( number )
number
The angle, in radians, whose tangent is number, in the range [-Pi/2..Pi/2].
Atn returns the arctangent of the argument number as a Double within the range of -Pi/2 to Pi/2. The arctangent is the inverse of the Tan function. The returned angle is measured in radians (not degrees).
The output would be:

Parameters
number
A number.
Return Value
The angle, in radians, whose tangent is number, in the range [-Pi/2..Pi/2].
Description
Atn returns the arctangent of the argument number as a Double within the range of -Pi/2 to Pi/2. The arctangent is the inverse of the Tan function. The returned angle is measured in radians (not degrees).
Example
Print "Pi ="; Atn ( 1.0 ) * 4
Print Atn ( 4 / 5 )
Print Atn ( 4 / 5 )
The output would be:
Pi = 3.141592653589793 0.6747409422235527
