Proof step 8 from proof cast-max (previous step)

0 < cast(1, j) ⊦ # int2bits(cast(1, j)) = 1

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 9:
⊦ cast(1, j) ≠ 0 → cast(1, j) = ~1

Rule argument

name: cast-one rotate: F subst: [j] → [j]

Additional information

Used simplifier rules: ⊦ i < j ∧ 0 ≤ i → 0 < j; (forward) Used terms: j
