Proof step 75 from proof bib-neg-high (previous step)

~128 ≤ i, ~128 ≤ i % 256, i < 0 ⊦ i = i % 256

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: int-div inst: name: mod-zero-05 seq: ⊦ abs(i) < j → i % j = i subst: [j, i] → [256, i] flags: rewrite
