Very surprised to see that the "Canon Canola F-11 37" returns the same value as most HP products. Does it mean that HP sold some source code or Canon stole their patent?

No. The Canola F-11 returns 9,000417403 just as many HP calculators, simply because that's the exact "forensic" result for a perfectly accurate 10-digit calculator. The result simply shows that Canon did their homework as well as HP.

As already pointed out: the "perfect" result is not 9. For a calculator with 10 digit precision it's actually 9,000417403. A perfect 12-digit device should return 8,99999864267.
