Proof step 14 from proof ushort-pos-01 (previous step)

0 < i, 32767 < i, i < 65536, 0 ≤ i, s2i(i2s(i)) < 0 ⊦ s2i(i2s(i)) + 65536 = i

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

name: sis-pos-high rotate: F subst: [i] → [i]

Additional information

Used simplifier rules: i0 ≠ 0, i0 ≤ i ⊦ (* i) < j → (* i0) < j;% ⊦ i < j → ¬ j < i;% ⊦ ¬ i ≤ j ↔ j < i;%0 < j ⊦ 0 ≤ i ∧ i < j → i % (* j) = i;% ⊦ i + (j - i) = j;% ⊦ i + j + i0 = (i + j) + i0;% ⊦ i + j = j + i; Used terms: i
