Any number of kills divided by zero deaths: _?

[r_Issimo2 1,495]

When you kill and not get killed in a battle match we get _ instead of numbers. What does _ means?

 

I was looking for answers and found that any number divided by 0 have a result called undefined.

 

But some say the result should be infinity. 

 

 

Others say not so fast.

 

 

In Tanki _ doesn't tell us anything about the number of kills made, and using infinity will be the same.

 

i suggest Tanki should just show the number of kills and the the zero death, for example 26/0. As if that's the final result because there's no other beyond that.

 

What do you think?

The long dash "–" just represents an undefined number and/or invalid entry. It's a standard representation, so I see no issues with it whatsoever.

I don't see why it should equal infinity. The video you showed suggests that proof of such a theory is that when the denominated gets smaller, the result becomes bigger, so zero would have to equal the largest number; infinity. But that's not proof. You can't divide by zero, because to divide there must be a devision, and zero isn't a division. Hence, there's no answer; undefined. :D

 

Besides, division is multiplication backwards.

 

100 ÷ 10 = 10

10 x 10 = 100.

 

If 100 ÷ 0 = ∞

∞ x 0 ≠ 100

∞ x 0 = 0*

 

Just like zero times any number equals zero because you are taking nothing and multiplying it, so too any number divided by zero is undefined because you aren't dividing it to begin with.

 

To put it into perspective, you're K/D is precisely your kills divided by your deaths. You want to take these three people you killed, and divide it by the amount of times you died. So if you never died, you can't divide it.

 

Repetitive and simple.

Spam ^

 

Anyways the overall KD shown in the ratings is pretty much good, since they add all kills and all deaths so it is no problem at all.

Problem would have been when they averaged KDs from each battle, then TO should have to provide a standard for 2/0 or 10/0 .....but that would be complicated.

 

So its irrelevant to discuss what does - means, as its simply does not matter, also not dying in 15 minutes is a feat itself, so no number in the vast domains of the universe can express your feat so TO keeps it undefined :D  :P  ;)

[r_Issimo2 1,495]

Good replies among the trolling.

 

If 100 ÷ 0 = ∞

 

∞ x 0 ≠ 100

 

∞ x 0 = 0*

"Infinity (symbol: ∞) is a concept describing something without any bound or larger than any natural number." - Wikipedia

 

"100 ÷ 0 = ∞" - I say this could be acceptable because 'infinity is a symbol"

 

"∞ x 0 ≠ 100", "∞ x 0 = 0*" - But here we can say that you can't use that symbol, or we can say that the answers to these are undefined and leave that problem for others while we use ∞. ;)

If anyone wants to get a better insight go here https://en.wikipedia.org/wiki/Indeterminate_form

 

The forms are indeterminate forms as we can't approach these numbers even through limits.

If you draw a graph of these functions you will never ever touch the axis.

 

If you studied high school you must have studied functions like 1/x

When you draw them one a graph they give values except for 1/0 i.e. x=0.

 

If you look at the graph 1/x you will see that when you approach zero from right side, the blue line is going to infinity so people assume 1/0 is infinite.

But look closely when you go to left from 0 the line is now going to minus infinity.

 

So what does it mean? How can a number 1/0 be very big for one instance and very small in other instance  (minus infinity means a very small number)?

So all the assumptions that any number divided by 0 equals infinity are completely false and fake.

 

You can't decide what is the nature of 1/0 as when u look at the graph from negative side its very small and from positive side its very big.

That's why its not defined, so how can any game dev define it?

 

Discussion Closed.

At least in Tanki, the opposite of infinity could be 0, because if you haven't killed a tank but you die at least one time your K/D is 0.

 

1/0 = ∞

1/1 = 1

0/1 = 0

Go on... Issimo

You provide any good proof of 1/0 is infinity.

I would prefer this:

 

0/1 = 0

1/1 = 1

1/0 = 1/0

 

Simple and tells the number of kills.

Makes no sense.

The first video is just horrid.

[LOLKILLERTOTHEDEATH 1,921]

It is undefined as has been said. Imagine doing it. You put two outside the long division symbol (for example) and the zero on the outside. Now what do you multiply 0 by, in order to get 2? nothing, that is. You cannot multiply the 0 by anything to get 2. Whether you put in a -100 or 771, the result will always be 0, thus you can say (if you go like 47 kills, no deaths) that I got a KD ratio of infinity, because technically speaking, even if you  put 47 on the inside and 0 on the outside and use positive infinity as the quotient, you will still not be able to divide.

If it can't be infinity...

 

1 ÷ 0 = ∞

 

because of this...

 

∞ x 0 ≠ 1

 

then it can't be undefined either...

 

1 ÷ 0 = _

 

because of this...

 

_ x 0 ≠ 1

The thing here is that infinity is not a real number. It's an abstract concept. Any number divided by zero is NOT infinity. If I took infinite zeroes and added them up, I still get zero.

Except for one major flaw. ∞ is not not a number in the way that you are trying to use it. Plug it into an equation and do algebra on it and you break mathematics. You have to work with it in its own habitat

Actually, it is, in its own habitat. Something like hyperreal or surreal numbers? Anyways, infinity is a group. 1/0 = aleph null

I don't think it should be considered a number, and because of that it can't be used in equations like ∞ x 0 ≠ 1.

 

But the answer to 1/0 could still be ∞, because the number of 0s in 1 is infinite, it just keep going and going.
