Proof step 14 from proof fits-law-mod (previous step)

⊦ i < 0, b2i(by1) = 0, i % b2i(by1) = b2i(i2b(i % b2i(by1))), ¬ i % b2i(by1) < ~128 ∧ ¬ 127 < i % b2i(by1)

Heuristic simplifier applied rule simplifier

Used simplifier rules: i0 ≠ 0, i0 < i ⊦ (* i) < j → (* i0) < j;% ⊦ i < j ∧ 0 < i → 0 < j ∧ 1 < j; (forward)% ⊦ i < j ∧ 0 ≤ i → 0 < j; (forward)% ⊦ 0 ≤ i ∧ j ≠ 0 → ¬ i % j < 0;% ⊦ i < (* j) ∧ j < 0 → i < 0; (forward)% ⊦ i ≤ j ∧ 0 ≤ i → 0 ≤ j; (forward)% ⊦ ¬ i < j ↔ j ≤ i;
