Variable radix : Z.
Hypothesis radixMoreThanOne : (1 < radix)%Z.
Let radixMoreThanZERO := Zlt_1_O _ (Zlt_le_weak _ _ radixMoreThanOne).
Hint Resolve radixMoreThanZERO: zarith.
Let FtoRradix := FtoR radix.
Local Coercion FtoRradix : float >-> R.
Fixpoint maxDiv (v : Z) (p : nat) {struct p} : nat :=
match p with
| O => 0
| S p' =>
match ZdividesP v (Zpower_nat radix p) with
| left _ => p
| right _ => maxDiv v p'
end
end.

Theorem maxDivLess : forall (v : Z) (p : nat), maxDiv v p <= p.
