How about:

class legendSlider : public puSlider
{
protected:
  char legendbuf [ 10 ] ;

public:
  void doHit ( int button, int updown, int x, int y )
  {
    puSlider::doHit ( button, updown, x, y ) ;

    snprintf ( legendbuf, 10, "%.2f", getFloatValue () ) ;
  }

  legendSlider ( int minx, int miny, int sz, int vertical = FALSE ) :
    puSlider ( minx, miny, sz, vertical )
  {
    setLegend ( legendbuf ) ;
  }
} ;
