Point coordinates after a certain angle of rotation about another point

Double X = vec_endPoint_rotate.x ();
 Double Y = vec_endPoint_rotate.y (); 

Double DX = vec_center_rotate.x ();
 Double Dy = vec_center_rotate.y ();
 // a point (x, y) about an arbitrary point (dx , dy) the coordinates of a rotated clockwise 

Double XX = (X - DX) * COS (angleParam VC_PI * / 180 [ ) - (Y - Dy) * SiN (angleParam VC_PI * / 180 [ ) + DX;
 Double YY = ( X - DX) * SiN (angleParam VC_PI * / 180 [ ) + (Y - Dy) * COS (angleParam VC_PI * / 180 [ ) + Dy;
