Vector bearing returns integer

[luppiale]

The 2 methods of Vector class returns integer instead of float value.

public function initialBearing()
    {
        Ellipsoid::checkCoordinatesEllipsoid($this->from, $this->to);

        $latA = deg2rad($this->from->getLatitude());
        $latB = deg2rad($this->to->getLatitude());
        $dLng = deg2rad($this->to->getLongitude() - $this->from->getLongitude());

        $y = sin($dLng) * cos($latB);
        $x = cos($latA) * sin($latB) - sin($latA) * cos($latB) * cos($dLng);

        return (float) (rad2deg(atan2($y, $x)) + 360) % 360;
    }

Using % with float variables cast it to integer losing a lot of precision.
If u want an angle between 0 and 360 you can do something like this

$angle = rad2deg(atan2($y, $x)) + 360;
return $angle > 360 ? $angle - 360 : $angle;
