Meme of two women fighting while a man smokes from a pipe in the background.
The women fighting are labeled "mathematicians defining pi" and "engineers just using 3 because it's within tolerance"
The man smoking is labeled "astrophysicists" and the pipe is labeled "pi = 1"
Electrical engineer. Never used 3. Always 3.14. don't really get the joke.
I've seen some blueprints who use 3.5. I guess it's close enough but definitely not too small
Strange. If you're going to use a decimal point, why not the right one?
You are correct, I used the wrong one for my region but according to Swedish Wikipedia (bad source) the US and UK uses a . If that is incorrect I'm happy to be corrected!

LOL. That's not what I meant. Unfortunately it is what I said.
What I should have said is, if you are going to use a number after a decimal point (or comma in Europe) then why not use the right number. My bad.
I just use the pi from my calculator or numpy/matlab. But I'm often too lazy for vacuum speed of light and use 3e8 m/s.
That's close enough for radio. You can't cut an antenna much closer than that precision, and it'll stretch or shrink with temperature anyway. I guess the error could add up enough to be a problem in lengths of fibre optic cables, especially as they run at about c/3
