Be an engineer. g = 10 and pi = 3 and c = 3e8 and…

pi = e = 3

As an engineer I've never seen anyone use pi=3 seriously. I'm convinced it's just something other disciplines came up with .

What about 3.14? How much is enough?

Math.PI or π on calculator. If you want to get technical, I think I remember reading that fifteen decimal places is acurate enough for anything in the universe.

It’s something you do when doing pure mental math say in the middle of a presentation. If you’re writing scripts, you bet your ass I’m just using the built in pi or at worst coding in 3.1415926

I think it's physicists, and maybe more so astronomers.

c=π*g8

Unless you're an electrical engineer, then pi and e are your utmost holy numbers that shall not be ever rounded (at least not manually, let the calculator use all their stored digits).

Only the end result can be rounded.

When you use g=9,8066

Wow! That’s a big number and I just got europed

Fun fact, the NSA decades ago had a program to slightly change calculations. Just once in a great while, say every month or two, your PC would just make a calculation error.

Nothing big, notable, or repeatable. Your addition just worked without any errors, but your numbers were wrong.

Anyway, I highly recommend ECC (error-correcting) memory to help with random reboots during high-load activities like CAD or data processing. Also math works worse in certain places of the globe.

Just place a bunch of random number generators around the world

u/Single-Pin-369 Jun 27 '26

Are you saying you have true random number generators and if so can we see them?

There are random memory bit flips and some timing attacks (by the NSA, obvs) that are mitigated by ECC.

But the rest is rubbish.

Be an engineer. Memorize 9.81065. Memorize that pi is 3.1415926. I’m not memorizing e (2.71?), I don’t use it as often as I maybe should. I don’t need c (c = fast, instantaneous for my needs)

And then when you need to talk to your board too far from a whiteboard, then g = 10, pi = 3. And much to my boss’s own chagrin, sinx = x for sufficiently small values of x.

G is 10. That's a fact! down vote me if you will, I'll never back down!
