Proof step 4 from proof long-is-cast (previous step)

i ∈long ⊦ i = cast(64, i)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 5:
0 < i, ~(2 ^ (i - 1)) ≤ j, j < 2 ^ (i - 1) ⊦ cast(i, j) = j
Proof step 6:
¬(0 < 64 ∧ ~(2 ^ (64 - 1)) ≤ i ∧ i < 2 ^ (64 - 1)), i ∈long ⊦ i = cast(64, i)

Rule argument

seq: 0 < i, ~(2 ^ (i - 1)) ≤ j, j < 2 ^ (i - 1) ⊦ cast(i, j) = j subst: [j, i] → [i, 64] rotate: F spec: intops inst: name: cast-mod-in
