Proof step 12 from proof int2bytes-rec-case (previous step)

i < ~128, ~256 < i, i < 0 ⊦ int2bytes(i) = i2b(~1) ' + i2b(i) '

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 13:
⊦ ~256 < i ∧ i < ~128 → int2bytes(i) = i2b(~1) ' + i2b(i) '

Rule argument

name: int2bytes-byte-neg rotate: F subst: [i] → [i]

Additional information

Used simplifier rules: i0 ≠ 0, i0 ≤ i ⊦ (* i) < j → (* i0) < j;% ⊦ ¬ i < j ↔ j ≤ i;% ⊦ i < j → (¬ ¬ j ≤ i ↔ false); Used terms: i
