did you know?

A "designer decimal" is a rational number with an "interesting" decimal expansion, like

        10000/9899 = 1.01020305081321345590....

Do you see what's interesting about it? I kinda dug the first few digits, but had to be told the real "hunh!" of it.

I'm betting on [livejournal.com profile] paperkingdoms to get it, of course. Anybody who can beat her to it wins her/his choice of my broken-necked giraffe candle or my root-beer-smellin' pencil!

Ooh, I got it, and I'm not even a math person! And I don't want to spoil it for others. Or should I?

However, while I am intrigued and would like to experience your root-beer-smellin' pencil at some point, I don't feel the need to own it.

Good on you, LLY! Go ahead and spoil it, I say ....

Perhaps I could interest you in some fancy Italian paperclips as a third option. Along with a sniff of the pencil, should you like.

Well then, who can resist? Every 2nd place is the sum of the two, 2-digit numbers before it. Whee.

indeed! know what the math people call that?

Hmm. Technically, that last "90" in your example breaks the code! Though I didn't even notice until reading that exotic definition which spelled out the first several numbers in the sequence.

maybe it's only interesting up to a point... :}

Ha! Rounding off clearly makes it less interesting.

I'm sure one of the other comments, which I swear I have not read yet, has already mentioned the fibonacci sequence, so I'm almost certainly out one root-beer-smellin' pencil. Each pair of digits is equal to the sum of the two preceeding pairs of digits.

Way cool.

I get it!

It's how much the price of gas should be today!

Late to LJ today. But I did get it. :^)
