Proof step 39 from proof rightshift-8 (previous step)

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

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

seq: abs(i) < abs(j) ⊦ i / j = 0 subst: [j, i] → [256, i] rotate: F spec: int-div inst: name: div-zero-02

Additional information

Used simplifier rules: ⊦ i < 0 → abs(i) = ~ i;% ⊦ ~ i < j ↔ 0 < j + i;% ⊦ (* j) < i0 + (* j0) ↔ j - j0 < i0;%i0 ≠ 0, i0 ≤ i ⊦ (* i) < j → (* i0) < j;% ⊦ i + j + i0 = (i + j) + i0;% ⊦ i + j = j + i; Used terms: 256, i
