Proof step 4 from proof long-min-01 (previous step)

l2i(lo) ∈long, i < 0, l2i(lo) < ~9223372036854775808, i ≤ ~9223372036854775808, l2i(lo) < i, l2i(lo) < 0 ⊦

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 5:
⊦ i ∈long ↔ ~(2 ^ 63) ≤ i ∧ i ≤ 2 ^ 63 - 1

Rule argument

name: inlong rotate: F subst: [i] → [l2i(lo)]

Additional information

Used simplifier rules: ⊦ i < j → (¬ ¬ j ≤ i ↔ false); Used terms: l2i(lo)
