It's a proven fact. I'd like to know what you think about it.

You're trying to get people riled up, but this is Scripters 2015 and no one's going to really care to argue about it like they would have in the past.

Yes I was


x = 0.999...
10x = 9.999...
9x = 10x - x = 9.999... - 0.999... = 9
x = 9x/9 = 9/9 = 1
x = 1
0.999... = 1

0.999 is confirmed to equal 1
Especially with rounding.
Rounding is always 100% factual
There is also mathematical proof with the mathematical rigor

obvious troll thread but idk why this was ever a discussion since 0.999 repeating can't be any more of a real number than infinity is

If it is equal to 1, and 1 is a real number, then 0.999... is certainly a real number.

Also, infinity too might be a real number depending on what you mean by “real number”. If you mean the set of real numbers, then it isn't.

But 0.999 is not a real number because 0.999 + 1 is not 2

True fact:
.999 + .999 = "fish"

Equality in Lua is not the same as equality in mathematics!

He meant 0.999 repeating, not an ellipse, but seriously, don't even bother. Threads like this were started up several times in old scripters, most of which to get people involved in a pointless argument.

By the way, if you run print(0.99999999999999999==1) in the command bar in ROBLOX Studio, you will get “true” in the output. This is another good example of how 0.999... is equal to 1.

This is another good example of how you are trolling on modern scripters cause every skid in the world thought that was valid on older but similar threads.

Aren't they the same thing, anyway?

quick eq


1 /3 == 1/3

1/3 == 0.33333...(repeating)

0.3333...(repeating) * 3 == 0.99999...(repeating)
1/3 * 3 == 1

therefore

1 == 0.99999...(repeating)

@CrowClaws

That's not a very rigorous proof…
