minus-squareConsole_Modder@sh.itjust.workslinkfedilinkarrow-up34·20 hours agoRounding pi to 3 is just the engineering way. It’s close enough to get the job done and then I don’t have to worry about decimal places. However, using pi=3 typically undershoots your calculations, so personally I like to use pi=4
minus-squareAceticon@lemmy.dbzer0.comlinkfedilinkEnglisharrow-up19·19 hours agoAn error margin of less than 5% (even better, biased in a known direction) is more than good enough for plenty of use cases. An error margin of more than 25% on the other hand, is seldom acceptable.
minus-squareConsole_Modder@sh.itjust.workslinkfedilinkarrow-up16·19 hours agoNah, it’s fine. Trust me I use pi=4 in every calculation I do that uses pi and I haven’t ever run into any issues at all (I’m not that type of engineer, I never do anything with pi)

It’s called safety factor
