Proof step 10 from proof test-sqrt-02 (previous step)

⊦ sqrt(mkDecimal(2, 0).int * 10000) = 141

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 11:
⊦ ¬(i % 10 = 0 ∧ j ≠ 0 ∧ i ≠ 0) → mkDecimal(i, j).int = i
Proof step 12:
¬(2 % 10 = 0 ∧ 0 ≠ 0 ∧ 2 ≠ 0) ⊦ sqrt(2 * 10000) = 141

Rule argument

spec: decimal inst: name: intvalue-base seq: ⊦ ¬(i % 10 = 0 ∧ j ≠ 0 ∧ i ≠ 0) → mkDecimal(i, j).int = i subst: [j, i] → [0, 2] flags: rewrite
