Proof step 1 from proof int2bytes-len-neg256 (conclusion)

⊦ ~256 ≤ i ∧ i < ~128 → # int2bytes(i) = 2

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
~256 ≤ i, i < ~128, i < 0 ⊦ # int2bytes(i) = 2

Rule argument

Additional information

Used simplifier rules: ⊦ i ≤ j ∧ j < j0 → i < j0; (forward)% ⊦ i < (* j) ∧ j < 0 → i < 0; (forward)
