Proof step 47 from proof sis-neg-high (previous step)

¬ j < ~1, 16 < # int2bits(j), i0 * 65536 + j < 0, i0 ≤ 0, j ≤ 0, i0 * 65536 + j < ~32768, ~32768 ≤ j, abs(j) < 65536 ⊦ s2i(i2s(bits2int(lastn(16, int2bits(i0 * 65536 + j))))) = j

Heuristic simplifier applied rule simplifier

Additional information

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