Proof step 1 from proof square-sqrt (conclusion)

⊦ mkDecimal(0, 0) ≤ dec → mkDecimal(sqrt((dec * dec).int), (dec * dec).scale / 2) = dec

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
mkDecimal(0, 0) ≤ dec ⊦ mkDecimal(sqrt((dec * dec).int), (dec * dec).scale / 2) = dec

Rule argument
