Returns the arctangent of a number
Syntax
Usage
result = Atn( number )
Parameters
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
