The poster is right: "even 1" would not terminate. But it is clearer this way:

let rec even n = (n = 0) or not(not_odd(n-1))

and not_odd n = (n = 0) or not(even(n-1));

It's like Bill & Ted's Bogus Journey: not not not not excellent.

Here is another possibility:

let rec even n = (n = 0) || odd(n-1)

and odd n = (n <> 0) && even(n-1);

Ch3: Introducing Functional Programming

In section 'Defining Recursive Functions' (right after the badFactorial example ;-)) I guess:

let rec even n = (n = 0) or not(odd(n-1))

and odd n = not(even(n-1))

should be:

let rec even n = (n = 0) or not(odd(n-1))

and odd n = (n = 0) or not(even(n-1))

My URL is intranet so not available but I am creating a blog on learning this language (know all types of commercial languages so far only) because I find it beautiful and I can already see that features are flowing from this language (or functional languages) into other languages, not only C++, C# and VB.NET... Java is coming out with F3!!!!!

Hi Don,

I'm really enjoying learning F# (and using what I learn on 'downstream' ;-) languages like C# 3 and C# 2) - is the book still on target re its publish date? Having enjoyed the 7 odd chapters you've kindly posted so far I look at the TOC and well... drool. Thanks for the awesome language.

Kind regards,

.tom

Chapter 4: Imperative Programming with F#

Page 14:

let sum n m =

let mutable res = 0

for i = n to m do

res <- res + n /// Is it i instead of n?

res

By the way, chapter 10 refers to Windows forms...I hope you concentrate on WPF. I also hope that you expand on "Imperative Reactive Programming," perhaps something like frtime, yampa, etc. I hope you release rest of the book as draft chapters within the next couple of weeks so I can do a demo at work ;)

Hi falcon,

A big new release is indeed coming soon: we'll start blogging about it shortly. We also took a bit of well-earned a break over Christmas!

Cheers!

F# updates have slowed down recently...are we to expect a big, juicy, update soon?

Is there a hint on the table of contents anywhere? I'd like to have a sense of the chapters-to-be.
