Proof step 3 from proof test-truncate-01 (previous step)

¬ abs(2) < mkDecimal(314159265358979323844, 20).scale ⊦ truncate(mkDecimal(314159265358979323844, 20), 2) = mkDecimal(314, 2)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 4:
mkDecimal(314159265358979323844, 20).scale ≤ 2 ⊦ truncate(mkDecimal(314159265358979323844, 20), 2) = mkDecimal(314, 2)

Rule argument
