ATan2
Angle = ATan2 ( Y , X )
Angle = Atn2 ( Y , X )
This function computes the arc tangent of the two variables
X and
Y. It is similar to calculating the arc tangent of
Y /
X, except that the signs of both arguments are used to determine the quadrant of the result.
The function returns the result in radians, which is between -π and π (inclusive).
This is the same function as
Ang except that the arguments are inverted.
Example
Print Deg(ATan2(1, -1))
