Proof step 20 from proof int2bits-rec-2pot-neg-02 (previous step)

uint2bits(~(j % 2 ^ i)) = [], 0 < i, j + 2 ^ i ≤ 0, j + 2 ^ i < i, j < 0, 0 ≤ i, j + 2 ^ i < j % 2 ^ i, 0 < j % 2 ^ i ⊦ j % 2 ^ i = 0, sgn(bitsinvert(uint2bits(~(j / 2 ^ i))) +1 + mklist(false, i→n(i))) = int2bits(j / 2 ^ i - 1) + fillsgn(i→n(i) + 1, int2bits(j % 2 ^ i)).rest

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

seq: ⊦ i < 0 ∧ j ≠ 0 → ¬ 0 < i % j subst: [j, i] → [2 ^ i, j] rotate: F spec: int-div inst: name: mod-grz-01

Additional information

Used simplifier rules: ⊦ i + j + i0 = (i + j) + i0;% ⊦ i + j = j + i;% ⊦ ¬ i < j ↔ j ≤ i;% ⊦ i < j → (¬ ¬ j ≤ i ↔ false);% ⊦ 0 ≤ j → 2 ^ j ≠ 0; Used terms: 2 ^ i, j
