Comment on PI is what
F4lcon@discuss.tchncs.de 8 months agoSo? You think you’ll get the correct result by using 3? Or 3.14? Not quite. You can only get infinitesimally close to the correct result by increasing digits of pi.
And of course, if you really need that circumference for something critical, guess what? You use the things people developed for this very problem, software packages, and so on. And of course, you get it double checked, triple checked.
If it’s assume pi is 5, it’s not misinformation. If they point guns at kids and say it’s 5 for real, then yes.

Or you could just use 3.14 which is infinitesimally more correct than 5, not lie about the number and aim for correctness and accuracy so people learn how to do things right the first time.
If you can’t handle a few decimal points then you aren’t ready for pi, go back to third grade.

I don’t think you understand what infinitesimally means! It means the opposite- you want to use ‘infinitely’ there.
Now, not being a condescending asshole, I really take issue with you calling an approximation a ‘lie’. And honestly, who’s multiplying decimal points mentally? That’s difficult. Use a calculator. Want to avoid calculators for an exam? Simplify! That’s why they use 5 and not 3.14.

That’s a bullshit excuse. 3 could be argued but 5 is straight disinformation. And I do multiplication of decimals in my head because I was taught how to in school, that’s how far behind the US system is.

That’s impressive. Mental math isn’t one of my talents to be honest. And let’s agree to disagree about the disinformation.
