>>> int(1.999999999999999) 1 >>> int(1.9999999999999999)

>>> .1 + .2
0.30000000000000004

Yes, that's right.

>>> print(Fraction('0.1') + Fraction('0.2'))
3/10

Obviously, since 1.99999... is equal to 2, then at some point it flips over from being in the 1 to the 2 range. Kudos to python for figuring out that happens at 16 9s.

oh boy...here we go again

In theory it's not equal but in every practical situation it's equal.

1/9 = 0.111...
9 * 1/9 = 9 * 0.111...
1 = 0.999...

>>58564225
Thanks anon I did.

>>58562438
You think that's weird?

1 + 2 + 3 +4 +5 +... = -1/12

>>58562089

it's almost as if the computer has a finite amount of memory and you just passed the max amount of 9s it can handle before it rounds it off to save memory

that's not how this works at all but you've kind of got it I guess

Ramanujan summation is basically bullshit.

Nice try, but no. 1/9 equals zero followed by an infinite number of 1s. However, infinity minus infinity equals infinity, so no matter how many 1s you have following the zero (even if you have an actual infinite number of them) you still need to add an infinite number of 1s for it to be exactly equal.

Try using decimal.Decimal if you actually care about precision

That sum doesn't actually converge to -1/12. That is just what brainlets that don't understand analytic continuation interpret it as.

what you should be saying is
>the analytic continuation of riemann zeta function with an input of -1 is equal to -1/12

this video explains it pretty well even if it's over twenty minutes long
