.999999...=0!

Does 0! = 1? How does that work?

I'm proud to have been the first response in that other thread AND to have never looked at any more responses.

only .99999 recurring=1, i.e.the series .9999..., wheras the number .999 (where there is a defined number of decimal places) is not equal to 1.

all that matters is that in the real world anything within the range [0.5,1.5) can equal 1 depending one the precision of the tools you use to measure.

Debating whether or not .999... is equivalent to 1 is trivial since normal people do not have any means to measure that precisely.

Now, if you were able to deal with things in terms of Planck's lengths, you might have an arguement since no length can exist beyond this precision, thus rendering .999... (or any similar nonterminating decimal) impossible, but only a select few people care remotely about that.

interesting point. However, .999... does not need to come from a measurement. i.e. how long in an inch, in cm's? It's exactly 2.540000000000000000000000000... exactly (by definition) However, there is no way to measure exactly 1 inch beyond the precision allowable in terms of Planck's lengths. Thus, 1 is as meaningless as .999... And, they are still exactly the same length.

DrPizza is correct

if you don't believe that .999... = 1, then you are a retard in mathematics

they are EXACTLY equal, there is no difference between the numbers

yeah, someone explain this one. 0.999... = 1 is so old. 😛

0! = zero factorial = 1

That's not an explanation, it's a demonstration.

This is an explanation.

I didn't realize you wanted an explaination

Yeah, it wasn't very clear 😉

Neither of these is a proof though. Formal mathematics proofs are a bit lengthier and require a little bit more understanding of some math symbols. Take my word for it though, there are dozens of valid proofs that .999... = 1. There is not one single valid proof which contradicts it.

I hate to contradict the great DrPizza, but you're wrong. There is not one single valid proof which contradicts it in the number system we use. If you use hackenstrings as the basis of your number system, 0.9999... != 1.

I stand corrected. You are right, I was wrong.

Wow... this i gotta see

Actually, someone else pointed that out in the old 0.9999..... thread. I was kind of surprised that this was true myself.
