| ### Function HenselLift ( elt-alg^pol F, elt-fld^pad x, elt-ord^rat k ) -> elt-fld^pad ### Description Hensel lift x, an approximate root of F which satisfies the Hensel condition, to a better root of precision >= k. ### Examples x_F5 := pAdicField(5);; x_F5P:= PolynomialAlgebra(x_F5); x_f:= x_F5P.1^2+1;;x_x:= Element(x_F5,2);;HenselLift(x_f,x_x,10);
