I would like to present an unusual take on computing the Fibonacci
sequence using Javascript. Please try out the following link in
Firefox (sorry, having problems with other browsers): http://webstervanrobot.com/
Click the "multi step" link to see it in action.
I am posting this mostly for entertainment value, and to show off some
of the power of Javascript. But I'm also hoping to solicit some
advice for making this work in other browsers.
Enjoy!

Has there ever been an attempt to write a Javascript-based
Javascript implementation?
Yes, at least 3. E.G:-
<URL: http://en.wikipedia.org/wiki/Narciss...aScript_engine) >
I'm not sure what the benefit would be...maybe the
ability to debug itself?
A pre-request of writing an ECMAScript engine (assuming the result was
a 100% conforming implementation) in ECMAScript would be an ability to
fully understand the language (all of it, from tokenisation through to
execution). The result could be a useful code manipulation/
verification tool for use in browser environments, but otherwise might
be pretty pointless.
Most of the existing attempts (including Narcissus) 'cheat' and end up
using the underlying language for things like regular expressions
instead of implementing them themselves.

It seems like the manipulation/verification problem is a good one to
solve. You don't necessarily need self-hosting to achieve it, but
having the lower level tools in Javascript obviously opens the doors
for lots of people to improve it.

Understandable.

How do you decide what is safe? Even a reputable site like google is full
of other people's links. Or do you just mean that you do not trust the
people who post here?
Well, essentially the best way is to use tools like the AVG SafeSite
scanner - but that will not track links in emails, so as a general
rule you just don't use them.

Hi everybody. I've been reading posts a year old about the fibonacci

related, I'll share my own notes as well.
On another newsgroup there is an ongoing discussion about the famous
fibonacci sequences, and a fine program written by a poster got my
attention so just for fun I wrote one myself and put it on the web just
about two days ago. It can be found on the site

Hello, I am trying to teach myself C++ while babysitting a stable network in Iraq and have put together a program to display the fibonacci sequence. It works with long and long double(output in exponent though)
After sequence 47 using long type the program won't display the output properly (I am assuming because of size limit of type) so I switched type to unsigned long and now number 49 outputs as 512559680 when it should be 4807526976

Question Details:
Write a program to find and print a Fibonacci sequence of numbers. The Fibonacci sequence is defined as follow:
Fn = Fn-2 + Fn-1, n >= 0
F0 = 0, F1 = 1, F2 = 1
Your program should prompt the user to enter a limit and indicate whether the last number in the sequence printed is either even or odd.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
