I was studying rules for numerals here: http://en.wikibooks.org/wiki/Esperanto:_A_Complete...

and have several questions:

1. Why the digit word is sometimes separated from the corresponding power number, and sometimes not. For example:

Tri miliono dudek du mil sepcent dudek naŭ = 3*10^6 + (0*100 + 2*10 + 2)*10^3 + 7*10^2 + 2*10^1 + 9*10^0 = 3 022 729

Why are "dudek" and "sepcent" written together. While "Tri miliono" and "du mil" are written separately?

2. How to say x in power y, in case I'd like to speak about numbers in exponent representation:

"eks en y grado"?

For example, I'd like to say in Esperanto: "two point fifty seven twenty three times ten to the six" = 2.5723*10^6

Is it like this: du punkto kvindek sep dudek tri multipliki dek en ses

Only cent and dek are written together.

I'm not sure about that, perhaps somebody can help here. I would say:
du komo kvin sep du tri multiplikita per dek potencita per ses

How pointless a word radical can be? Is ipsilono for y the winner? WHAT THE FUCK?! I thought the names of the letters were the bookstaves themselves (the sound they correspond) + o in case of consonants.

What are the names for other bookstaves?

Oijos: I thought the names of the words were the bookstaves themselves (the sound they correspond) + o in case of consonants.

Is Y a consonant? For example in Polish it isn't. Moreover, Y is not a part of the Esperanto alphabet. So which sound should it represent?

Y is not a consonant. I did not say so. But you are right, y is not part of the Esperanto alphabet. LOL, what a mistake! I forgot that! Esperanto has very few vowels! And that (that Y is not in Esperanto) explains partly the stupid name. Still, why can't the name for Y be more "like Y"?? For example the name for X is ikso.

Because it's taken from the Greek name for the letter...

Sounds like you're having a major brain fart, Oijos!

Speaking of which, is there any sort of Esperanto phrase or word for "brain fart?"
