Engineers round it up to 2 because "close enough for practical purposes." Statisticians approximate it to 1.7 because decimals are just suggestions. Physicists calculate it to five decimal places because they're sooo precise.
And then there's mathematicians... *maniacal laughter* PURE CHAOS! They're having an existential crisis because √3 is an irrational number that continues FOREVER without pattern! They can't even write it down completely! It's just... itself! The mathematical equivalent of "it is what it is" but with infinitely more screaming!
