output operator of Esri::ArcGISRuntime::Point

I create two point and put them to QDebug/qCritical.

But i get unexpected results:

const Viewpoint &vp = mapGeoView->currentViewpoint(ViewpointType::CenterAndScale);
const Point &mapCenter = static_cast<Point>(vp.targetGeometry());
Point myLocation = mapCenter;
Point skyLocation = Esri::ArcGISRuntime::Point(mapCenter.x(), mapCenter.y(), 99999, sr);
qCritical() << " myLocation =" << myLocation << " z=" << myLocation.z();
qCritical() << " skyLocation=" << skyLocation << " z=" << skyLocation.z();

Output:

myLocation= 8.89179 53.0743 5.64578e-316 3.95253e-322 z= 0

myLocation = 8.89179 53.0743 5.64578e-316 3.95253e-322 z= 0
skyLocation= 8.89179 53.0743 5.74185e-316 3.95253e-322 z= 99999

The 1st and 2nd are clear.

The 3rd should be the z-value, right? But why 5.64578e-31?

The 4th is most likely the m-value (3.95253e-322) right?

Thx

Norbert, this looks like a bug. I think there is some implicit type conversion that is happening. The x and y are correct, and the others are not z or m - they are just wrong. Can you please log a bug through support so that this gets put into the support system? Thanks for reporting! In the meantime, maybe you can use toJson() instead for debugging geometries.

Hi Luke,

thanks for your information and tip (toJson)

I logged a bug:

Esri Support Case Number 01903553.
BUG-000103765 : The z and m value of Esri::ArcGISRuntime::Point provides incorrect result.

thx
