Proof step 17 from proof cast-mod-neg-low (previous step)

j % 2 ≠ 0 ∧ j < ~1, j % 2 < 0, j < ~1, j % 2 < ~1, j < 0, 1 ≤ #(int2bits(j / 2 - 1) + true ') ⊦ bits2int((int2bits(j / 2 - 1) + true ').last ') = 2 + j % 2, j = ~1

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 18:
j % 2 < 0, j < ~1, j % 2 < ~1, j < 0 ⊦ j = ~1, j % 2 = 0, ~3 = j % 2

Additional information

Used simplifier rules: ⊦ m + n = n + m;% ⊦ (m + n0) + n1 = m + n0 + n1;% ⊦ m ≤ m + n;% ⊦ # boolvar ' = 0 +1;% ⊦ #(bits + bits0) = # bits + # bits0;% ⊦ i + j = j + i;% ⊦ i + j + i0 = (i + j) + i0;% ⊦ (* j) = i0 + (* j0) ↔ j - j0 = i0;% ⊦ bits2int(true ') = ~1;% ⊦ (bits + bits0) + bits1 = bits + bits0 + bits1;% ⊦ (bits + boolvar ').last ↔ boolvar;
