proposition: Theorem round_round_sqrt_radix_ge_4_FLX : (4 <= beta)%Z -> forall choice1 choice2, (2 * prec + 1 <= prec')%Z -> forall x, FLX_format beta prec x -> round_round_eq (FLX_exp prec) (FLX_exp prec') choice1 choice2 (sqrt x).
proof: Proof. intros Hbeta choice1 choice2 Hprec x Fx. apply round_round_sqrt_radix_ge_4. - exact Hbeta. - now apply FLX_exp_valid. - now apply FLX_exp_valid. - now apply FLX_round_round_sqrt_radix_ge_4_hyp. - now apply generic_format_FLX. Qed.
