0,99...=1.<br />
How can this be?<br />
<a href="http://en.wikipedia.org/wiki/0.999" target="_blank">http://en.wikipedia.org/wiki/0.999</a>...<br />
This totally crushes my faith in the universe.

I don't believe that 0.999... cannot be equla to 1.

0 . 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 . . . etc is so close to 1 that it doesn't matter if it is or isn't in fact actually 1. This topic has infuriated forum dwellers for the last 2 years.

I like it lol.<br />
<br />
makes sense....<br />
<br />
<br />
1/3 = .333333333333333333 infinitely.<br />
<br />
.33333333333333333 infinitely x3 = .999999999999 infinitely...<br />
<br />
and 1/3 x 3 = 1<br />
<br />
so...<br />
<br />
.99999999999999 infinitely = 1.<br />
<br />
AHHA. awesome!

Okay, if you know this thing, Im sorry then.<br />

Thats like saying a dog is a cat. 1 is not .999999 It may be congruent but not literally THE SAME THING, because its obvious they are not the same, one is 1. and the other .9999999... Weird.

Thats what this is about. I dont understand it.<br />
0,99... IS 1. Just like two parallel lines will meet in infinity.<br />
Mathematics proved that this is the chase.<br />
And yet 0,99 is obviously not 1.<br />
<br />
If 1 is not 1, but 0,99, what is what? Who am I?<br />
Does the universe even exist?

I think the whole .0999999... =1 thing is for practical purposes when performing calculations with such small figures. I can't imagine trying to work out a mathematical problem with those kinds of numbers. Inaccurate? Yes. Yet it's all for simplicity.

LOL! It's like being infinitely close, but no bannana. How frustrating for 999....!

</div>Actually, that doesn't work because you're trying to prove a proof with the thing you're proving.<br />
<br />
1/3 can't = 0.3_ until after you prove that 0.9_ = 1.<br />
<br />
It's also said that 1/3 is best represented in decimal as 0.3_. There is NO WAY to truly display the fraction 1/3 because we don't have half numbers).<br />
<br />

Yeah, technically, when you divide the fraction, you introduce loss. It is a weak premise. But, still...when you talk in terms of significant digits...it's freakin 1 LOL!
