Proof step 12 from proof less-totality (previous step)

0 ≤ abs(i2) ⊦ mkDecimal(i * 10 ^ abs(i2), abs(abs(i0)) + abs(i2)) = mkDecimal(i1, abs(i2)), mkDecimal(i1, abs(i2)) < mkDecimal(i * 10 ^ abs(i2), abs(abs(i0)) + abs(i2)), mkDecimal(i * 10 ^ abs(i2), abs(abs(i0)) + abs(i2)) < mkDecimal(i1, abs(i2))
