Detailed Description

A point with floating point precision.

Author: Franz Schmid One of the advantage of FPoint vs QPointF is that FPoint has consistent precision across platforms : the coordinates are systematically stored as double. QPointF uses the qreal typedef which is sometime double, sometime float.

FPoint has also some coordinate transformation functionalities not provided by QPointF.
