darctan2(y, x);
| Argument | Description |
|---|---|
| y | The y coordinate to calculate. |
| x | The x coordinate to calculate. |
Returns: Real
This function returns the inverse tangent of an angle y/x, where
y = Opposite side of triangle and x = Adjacent side of triangle.
Unlike darctan(x) the function darctan2(y, x) is valid for all
angles and so may be used to convert a vector to an angle without
risking division by zero, and it also returns a result in the
correct quadrant.
NOTE: The value returned is in degrees, not
radians.
val = darctan2(1, 1);
This will set "val" to the correct angle.
