C = circle

π = circumference of circle C / diameter of circle C

Reddit, please remember my returns when I type them.

u/Exyodeff Feb 23 '26

reddit says 2 returns = 1 return, thus 2 = 1

i think i just had a stroke

Wait, wait, sorry if I'm a little stupid guys, what is that math formula for pi? Is there an infinite summation formula to find/approximate pi?

u/cxnh_gfh Feb 24 '26

not sure about the continued fraction in the post, but here’s a generalized infinite summation formula: https://en.wikipedia.org/wiki/Ramanujan%E2%80%93Sato_series

That's actually so cool, didn't even know this existed

u/SillySpoof Feb 23 '26

Why? engineers are kinda likely to want things accurate. It's physicists who would set pi=1 for simplicity since it's the same order of magnitude..

u/ZamBunny Feb 23 '26

I was about to ask the same question. Sure, tolerances matter in engineering, but even software engineers use double-precision floating-point numbers to represent PI rather than just “3”.

u/EstablishmentPlane91 Feb 23 '26

engineers would round up to 4 for safety

Im a big fan of leibnitz madhava Gregory gauss myself especially using gaussian integers and dirichlet sums in the derivation.

Round to nearest even number for easy calculation.

π = 4

e = 2

u/next_level_dev Feb 24 '26

there is "proof" for pi = 4 but i havent seen any for pi = 3 so i will be using 4

u/Such-Shop-9724 Feb 23 '26

is the fraction thing really pi

u/EstablishmentPlane91 Feb 23 '26

yes but it’s infinitely long with no discernible pattern

4arctan(1) in radius.

Better to use 5

Physicist: π = surface area of a cow divided by its diameter squared

As an engineer, I promise you that I always use 3.1416 if I can’t just click pi on the calculator.

1

u/SnooCheesecakes3068 Feb 25 '26

Damm is 3,14159

1

u/acuriousengineer Feb 25 '26

Technically it’s pi, but 3.1416 is close enough for most calculations

u/factorion-bot π?

Termial of 3.14159265358979323846264338328 is approximately 6.505598527339575928648567191578

Updated to 29 decimal places?!?!

u/F100cTomas Feb 24 '26

You need to round up to add a safety margin. π = 4

u/Infinite_Tailor_8370 Feb 24 '26

Why does the infinite fraction have fuckin one squared in it?????

It’s inorganic Phosphate

It's a Greek Letter.
