Proof step 24 from proof int2int-lastn-negneg (previous step)

i = (bits2int(bits) + 1) * 2 ^ n→i(m) + bits2int(lastn(m, int2bits(i))), int2bits(i) = bits + lastn(m, int2bits(i)), # bits = # int2bits(i) - m, i < 0, lastn(m, int2bits(i)).first, m ≤ # int2bits(i), bits.first ⊦ bits = [], m = 0, bits2int(lastn(m, int2bits(i))) = i % 2 ^ n→i(m), i + 2 ^ n→i(m) = 0
