Proof step 13 from proof mkDecimal-maxScale-nle (
previous step
)
abs(j) < maxScale(i) ⊦ i / 10 ^ abs(j) = mkDecimal(i / 10 ^ abs(j), 0).int
User applied rule insert rewrite lemma
And obtained the following new goals
Proof step 14
:
⊦ ¬(i % 10 = 0 ∧ j ≠ 0 ∧ i ≠ 0) → mkDecimal(i, j).int = i
Rule argument
spec: inst: name: intvalue-base seq: ⊦ ¬(i % 10 = 0 ∧ j ≠ 0 ∧ i ≠ 0) → mkDecimal(i, j).int = i subst: [j, i] → [0, i / 10 ^ abs(j)] flags: rewrite, current
Additional information
Used terms: 0, i / 10 ^ abs(j)
