Proof step 17 from proof ushort-pos-02 (previous step)

~65536 ≤ i, i < 0, s2i(i2s(i)) < 0 ⊦ s2i(i2s(i)) = i

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 18:
~32768 ≤ i, i ≤ 32767 ⊦ s2i(i2s((* i))) = i
Proof step 19:
¬(~32768 ≤ i ∧ i ≤ 32767), ~65536 ≤ i, i < 0, s2i(i2s(i)) < 0 ⊦ s2i(i2s(i)) = i

Rule argument

name: num-issi rotate: F subst: [i] → [i]
