Atn
 
Returns the arctangent of a number

Syntax
Usage

result = Atn( number )

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 )


The output would be:
Pi = 3.141592653589793
0.6747409422235527
