Proof step 12 from proof fits-law-neg (previous step)

¬ 0 < ~ b2i(by), 16 < # int2bits(~ b2i(by)), b2i(by) ≤ 1 ⊦ b2i(by) + cast(16, ~ b2i(by)) = 0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 13:
16 < # int2bits(~ b2i(by)), b2i(by) ≤ 1, 0 ≤ b2i(by) ⊦ b2i(by) + cast(16, ~ b2i(by)) = 0

Rule argument

Additional information

Used simplifier rules: ⊦ i ≤ j ∧ 0 ≤ i → 0 ≤ j; (forward)% ⊦ j ≤ j0 ∧ j0 ≤ j1 → j ≤ j1; (forward)% ⊦ ¬ i < j ↔ j ≤ i;% ⊦ 0 < ~ i ↔ i < 0;
