[Qt-mobility-feedback] Fwd: Small Feature Request for QGeoCoordinate

[Jeffery MacEachern]

Hi David,

What are your thoughts on Craig's points below (from a while ago)?  I
didn't see any response at the time.

Given that altitude is a double, and distance is a qreal, it seems something like this would be a better:

Thanks,
