      I always learned 22/7 = 3.142

      Also close enough for most situations that don’t need extreme accuracy

        True that, and 22/7 is the first approximation I learned around 8th grade. But I had already learned π to 50 decimal places in 4th grade…

        So by 10th grade I was studying computer programming, on my own, not a school class. Anyways, I found myself fascinated by mathematical algorithms, and ended up (amongst other things) writing a decimal to fraction converter.

        When I chucked π through it, it gave me 355/113
