Proof step 18 from proof int2bytes-rec255-neg (previous step)

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

seq: ⊦ i < j - i0 ↔ i + i0 < j subst: [i0, j, i] → [256, 0, i % 256] rotate: F spec: int-abs inst: name: sub-ls-01

Additional information

Used simplifier rules: ⊦ 0 < j → ¬ j + i % j < 0;% ⊦ i + j + i0 = (i + j) + i0;% ⊦ i + j = j + i; Used terms: 256, 0, i % 256
