      (This came up on Square One TV when I was a kid Months typically have four seven-day weeks, plus a few days extra It is very tempting to round down and just say "one month = four weeks" But if you do that for the whole year, you've cheated someone out of 4 weeks out of 52)

      (That particular example, even though you'd think it's a fucking obvious one, is one that's been used to fuck over uneducated people in the wild before Hence you always count the number of weeks in a year by dividing 365 / 7 = 52 plus a day, not by adding up the months)

      Deep down he actually knows this and, much like some folks on Wall Street playing with rounding, he’s doing it with an agenda.

      There is no Wall Street scandal that resulted from people rounding numbers up instead of down, you don't understand what you're talking about and are not qualified to discuss it

      I said nothing about rounding up or down, just rounding. But in fact rounding up has been a problem. And then you speak of qualifications...! Quite the multilayered gaslighting operation you've got going. One quick example for your reference:https://www.cnbc.com/2018/06/22/sec-investigates-whether-companies-round-up-earnings.html …

      Well that's a fun fact I didn't know, and that I kind of doubt you knew until you googled it just now to own me What of it

      Note that this fun paper - which is indeed a cool paper - jokes about the term "quadrophobia", fear of the number four It is arguing that earnings reports improperly round up rather than down when the digit in question is 4, rather than 5 or higher

      It does NOT say that the SEC should ban the concept of rounding altogether in earnings reports and they should be printed with as many significant digits as the paper will hold Because that's absurd

      They're also not directly cheating anyone out of any money, this is a story about companies subjectively creating a more positive impression of themselves than they should in order to appeal to investors

      Everything about this story is a *demonstration* of what I mean when talking about "fuzzy math" Including the fact that actually punishing companies for "quadrophobia" is likely impossible because the amounts are so small for each instance - fractions of a cent - but add up

          Manipulation of rounding has consequences on Wall Street and elsewhere. Another piece for your reading pleasure. It's quite short. A nice little quote for ya: "Rounding necessarily results in a reduction of precision and the technique used can bias data when applied repeatedly.

          Yes, and it's an issue because rounding is inevitable and necessary It's exactly what I was talking about when I said "Sometimes 2+2=5" ("Both of these are two pounds, what's the big deal" "PUT THEM BOTH ON THE SCALE TOGETHER AND WE'LL SEE")
