Documentation of <QtGlobal> contradicts itself

The page at http://doc.qt.io/qt-5/qtglobal.html says "Several convenience type definitions are declared: qreal for double...", but, at http://doc.qt.io/qt-5/qtglobal.html#qreal-typedef, says "Typedef for double unless Qt is configured with the -qreal float option."

It should probably say, instead, something such as ""Several convenience type definitions are declared: qreal for double or float...".
