Proof step 2 from proof int2bits-neg-01 (previous step)

0 < i ⊦ sgn(bitsinvert(uint2bits(i)) +1) = int2bits(~ i)

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

name: int2bits-neg rotate: F subst: [i] → [~ i]

Additional information

Used simplifier rules: ⊦ 0 < j → abs(j) = j;% ⊦ abs(~ i) = abs(i);% ⊦ ~ i < 0 ↔ 0 < i;% ⊦ ¬ i < j ↔ j ≤ i;% ⊦ i < j → (¬ ¬ j ≤ i ↔ false); Used terms: ~ i
