to do with it. Wikipedia is a source-based encyclopedia, and when
executed properly, its articles will reflect the biases of its
sources. This should be mainstream, learned opinion in the field.

As for x:xs, the xs is meant to be the plural of x, and is
pronounced exs (I guess...).
Similarly, n:ns is one n followed by many more ens. Make sense?
I think this convention is often used in the Prolog community as well,
as in X|Xs.

No, not the trailing slash. The difference between a directory and its
contents is important enough. This is ususally encoded using a trailing
slash, but I'd rather not worry about that detail in a program.
What does Emacs do with double separators?

Is there anything that can be done (easily) to reduce the rounding errors?
The hint that I gave before is one easy way.
fib :: Integer - Integer
fib x = let phi = ( 1 + sqrt 5 ) / 2
in truncate( ( 1 / sqrt 5 ) * ( phi ^ x + 0.5) )
You run out
