Call UnionRectF to obtain the smallest rectangle with coordinates in floating points that include both R1 and R2. The union is returned as the Rect parameter.
UnionRectF returns True if the resulting rectangle is nonempty. If the resulting rectangle has a width or height that is less than or equal to 0, UnionRectF returns False.
