GenContFract.of_correctness_atTop_of_terminates

∀ {K : Type u_1} [inst : Field K] [inst_1 : LinearOrder K] {v : K} [inst_2 : FloorRing K],
  (GenContFract.of v).Terminates → ∀ᶠ (n : ℕ) in Filter.atTop, v = (GenContFract.of v).convs n

If GenContFract.of v terminates, then its convergents will eventually always be v.
