Proof step 22 from proof fix-bits2bytes (previous step)

# bits = m * 8 + n0, n0 < 8, # bits ≤ 8 * m ⊦ bits = [], n0 = 0, fix(m + 1, bits2bytes(bits)) = bits2bytes(fillsgn(8 * m + 8, bits))

Additional information

Used simplifier rules: ⊦ m * n = n * m;% ⊦ m + n ≤ m ↔ n = 0;% ⊦ (m + n0) + n1 = m + n0 + n1;% ⊦ m + n = n + m;
