Proof step 2 from proof int2bytes-last (previous step)

0 ≤ i, i < 128 ⊦ int2bytes(i).last = i2b(i)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
0 ≤ i, i ≤ 127 ⊦ int2bytes(i) = i2b(i) '

Rule argument

name: int2bytes-le127 rotate: F subst: [i] → [i]

Additional information

Used simplifier rules: ⊦ by '.last = by;% ⊦ ¬ i ≤ j ↔ j < i;% ⊦ i ≤ j → (¬ ¬ j < i ↔ false);%i + 1 = i0 ⊦ j < (* i0) → ¬ (* i) < j; Used terms: i
