Talk on Arithmetic with continued fractions. [Jan. 26th, 2005|07:37 pm]
Chaz Meyers
From the Philadelphia Linux User Group mailing list:
Multiprecision arithmetic algorithms usually represent real numbers as decimals, or perhaps as their base-2^n analogues. But this representation has some puzzling properties. For example, there is no exact representation of even as simple a number as one-third. Continued fractions are a practical but little-known alternative.
Continued fractions are a representation of the real numbers that are in many ways more mathematically natural than the usual decimal or binary representations. All rational numbers have simple representations, and so do many irrational numbers, such as sqrt(2) and exp(1). One reason that continued fractions are not often used, however, is that it's not clear how to involve them in basic operations like addition and multiplication. This was an unsolved problem until 1972, when Bill Gosper found practical algorithms for continued fraction arithmetic.
I'll explain what continued fractions are and why they are interesting, how to represent them in computer programs, and how to calculate with them.


It sounds like it could be either very interesting or very dull. :) Anyone interested in going with me? The "rehearsal talk" is at 6PM over at University of Penn.

Oh, come on. The quality of his piece of ass is not determined by hair. Well, it could be, if it's a particularly hairy bum, but I don't think you're talking about that kind of fro. But it's not determined on the basis of his head hair!

I dunno.... I'm not convinced, especially after living with you for two years.

Oh, sorry. Weds, Feb 2nd.

If you're interested in seeing the talk anyway, he's doing it again over at Haverford College on the 7th at 4:15. The UPenn talk is more of a "rehearsal" for that presentation.

There are more details about location/time in the email I linked to in the post.

Hmm, the original email isn't loading now, but I'll check it out later. Haverford college is more in my neck of the woods.

Hmm, I wonder if my calc teacher would mind me skipping for this.
