It does sometimes...
Other times it doesn't... other times=99.999999...% of the time(now lets see what does that equal)

EDIT: and I don't get the proof. why does it not equal infinity?

It equals 100%.

99.999999...%

My calculator gives me a syntax error there.

I wonder why it is the same as 0.999999999...=1 simple infinite series that don't switch signs and get less than the original when all operations are additiion

O_o how the hell adding an infinite number of positive numbers equals a negative one?

Math sure is weird.

Let's see if this rings a bell to programmers: It's a bit like signed numbers. 65535 = -1. 65535 = 1111111111111111 in binary. (in Axe. Sort of.)
Only in math, it's a perfect computer that has an infinite number of bits. But if you turn all of the bits on, then it becomes negative :D. 1+2+4+8+16+... = -1.

Well, maybe not, but that's the way I think of it. Still taking calculus, so I don't know the intricacies of this.

Also, strange followup: You've heard that you can't go colder below absolute zero, but it turns out that negative temperature is WARMER than an infinite amount of degrees. http://en.wikipedia.org/wiki/Negative_temperature

If I had mod powers, I could fix it.  Just do:

For raising to the imaginary power, you must work with positive real numbers (numbers that work with the natural log). If you want to use negatives to an imaginary power, you have to some even more advanced math playing :D so pretty much:
xi=cos(ln(x))+i*sin(ln(x))

1+1+1+1+1+1+1+1+1+1+1+1...... as a signed int, when it reaches 32767 (or something) DOES become negative :P

Yeah, but they were talking about real-life math, not 16-bit signed integers.  I still don't get it. How can 1+1+...=-1?
I will try it once i am finished dividing by 0.

Ok. That kind of makes sense in a sort of roundabout fashion.

Yep, it is one of those things where it kind of almost nearly comes close to possibly being probably understandable in a drawn out roundabout way, just like you said :D Really, you could prove it to be anything which is why infinity is regarded more as a concept as opposed to a number.
