Proof step 5 from proof long-band-add (previous step)

⊦ ¬ band(4294967295, i) + band(4294967295, j) < ~9223372036854775808, l2i(i2l(band(4294967295, i) + band(4294967295, j))) = band(4294967295, i) + band(4294967295, j)

Additional information

Used simplifier rules: ⊦ i + j = j + i;% ⊦ i + j + i0 = (i + j) + i0;% ⊦ i < (* j) ∧ j < 0 → i < 0; (forward)
