Proof step 6 from proof dec2int-zero (
previous step
)
⊦ i = 0, 10 ^ mkDecimal(i, 0).scale = 1
User applied rule insert rewrite lemma
And obtained the following new goals
Proof step 7
:
⊦ ¬(i % 10 = 0 ∧ j ≠ 0 ∧ i ≠ 0) → mkDecimal(i, j).scale = abs(j)
Rule argument
spec: inst: name: scale-base seq: ⊦ ¬(i % 10 = 0 ∧ j ≠ 0 ∧ i ≠ 0) → mkDecimal(i, j).scale = abs(j) subst: [j, i] → [0, i] flags: rewrite, current
