/lang/ang

# Ang

Angle = Ang ( X , Y )

This function computes the arc tangent of the two variables X and Y. It is similar to calculating the arc tangent of X / Y, 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 ATan2 except that the arguments are inverted.

To convert rectangular coordinates to polar coordinates, use Mag to get the distance and this function to get the angle.

### Example

    Print Deg(Ang(-1, 1))

    135
