Returns the angle whose tangent is the quotient of two specified floating point numbers
Class: Mathematical
Parameters: @y A number representing the y co-ordinate of a point
@x A number representing the x co-ordinate of a point
Syntax: @returnValue=@atan2(@y, @x)
Returns: An angle, Θ, measured in radians
Remarks:
The return value is the angle in the Cartesian plane formed by the x-axis, and a vector starting from the origin (0,0), and terminating at the point (@x,@y).
Multiply the return value by 180/∏ to convert from radians to degrees
Used in preference to @atan when the adjacent is very small
Example:
//Example for the mathematical @atan2 method
@x=1 //Set x co-ordinate value
@y=2 //Set y co-ordinate value
@result_rad=@atan2(@y, @x) //Calculate result in radians (= 1.10715)
@result_deg=@result_rad*(180/@pi()) //Convert radians to degrees (= 63.4349)
message(Angle in radians is + @result_rad + and in degrees is + @result_deg) //Display results message
