RealT & EndAngle()

End angle of arc, which proccedes clockwise.

RealT EndAngle() const

End angle of arc, which proccedes clockwise.

BooleanT FitLSQ(const Point2dSArray1dC & Pnts)

Fit to some points.

const Circle2dC & operator=(const Circle2dC & Oth)

Assignment.

RealT & Radius()

Constant access to radius.
