Proof step 5 from proof dec2int-zero (previous step)

¬(i % 10 = 0 ∧ 0 ≠ 0 ∧ i ≠ 0) ⊦ i / 10 ^ mkDecimal(i, 0).scale = i

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 6:
⊦ i = 0, 10 ^ mkDecimal(i, 0).scale = 1

Rule argument

Additional information

Used simplifier rules: scale-not-neg: ⊦ ¬ dec.scale < 0;%div-eq-same-01: j ≠ 0 ⊦ i / j = i ↔ i = 0 ∨ j = 1; from specification int-div%pot-zero-01: ⊦ 0 < i → (i ^ j = 0 ↔ j < 0 ∧ 1 < i); from specification int-pot
