Proof step 2 from proof bits2uint-not-neg-01 (previous step)

bits2uint(bits) < 0 ⊦

User applied rule insert lemma

And obtained the following new goals

Proof step 3:
⊦ bits2uint(bits) ≤ 0 ↔ bits2uint(bits) = 0

Rule argument

name: bits2uint-not-neg subst: [bits] → [bits]

Additional information

Used simplifier rules: ⊦ ¬ i ≤ j ↔ j < i;% ⊦ i < j → ¬ j < i;% ⊦ i < j ∧ i = i0 → i0 < j; (forward)% ⊦ i < j ∧ j = i0 → i < i0; (forward) Used terms: bits
