Proof step 19 from proof uint2bits-add-low-01 (previous step)

j0 < 0 ∧ 0 < i ∧ abs(j0) ≤ 2 ^ (i - 1), j0 < 0, 0 < i, 0 ≤ j0 + 2 ^ (i - 1), 0 ≤ 2 ^ i + j0, 0 ≤ i, 1 < j, 0 < j ⊦ j = 1, fillsgn(i→n(i) + 1, false ' + fillsgn(i→n(i), int2bits(j0))).rest = fillsgn(i→n(i), int2bits(j0))

Additional information

Used simplifier rules: ⊦ i ≤ 0 ∧ 0 ≤ j → i ≤ j;% ⊦ i + j = j + i;% ⊦ ~ i ≤ j ↔ 0 ≤ i + j;% ⊦ i < 0 → abs(i) = ~ i;
