Proof step 1 from proof inshort-sis (conclusion)

⊦ i ∈short ↔ s2i(i2s(i)) = i

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
⊦ ~32768 ≤ i ∧ i ≤ 32767 ↔ s2i(i2s(i)) = i

Rule argument

Additional information

Used simplifier rules: inshort: ⊦ i ∈short ↔ ~32768 ≤ i ∧ i ≤ 32767;
