class BOPTools_AlgoTools2D
    method:
void BOPTools_AlgoTools2D::AdjustPCurveOnFace
  (const TopoDS_Face& aF,
   const Standard_Real aFirst,
   const Standard_Real aLast,
   const Handle(Geom2d_Curve)& aC2D,
   Handle(Geom2d_Curve)& aC2DA)

The adjustment value for 2D curve has been calrified with precision value in parametric space

Test case for issue CR25285
