perlfaq4 error ? good catch: I am stupid

Zoop has asked for the wisdom of the Perl Monks concerning the following question:

Respected Monks,

I am not sure if its a right place to post this but its something I observed while reading through and I guess it might need correction if at all I am right.

In perlfaq,under the topic

How do I sort an array by (anything)?

Supply a comparison function to sort() (described in sort): 1. @list = sort { $a <=> $b } @list; The default sort function is cmp, string comparison, which would sort (1, 2, 10) into (1, 10, 2) . <=> , used above, is the numerical comparison operator.

Shouldn't it say "would sort (1, 10, 2) into (1, 2, 10)"

All said and done but I must admit about perl that I have not come across any other language (of course out of a handful which I boast I know) that has such an extensive documentation categorized in such a pretty way and accessible in so many ways :)

Shouldn't it say "would sort (1, 10, 2) into (1, 2, 10)" No. That would be numerical sort - but the default is string comparison, i.e. comparison of chars of strings leftmost first.	[reply]

More like: you were ignorent, and in your quest for knowledge you eyes glazed for just a second, your brain played a little trick. I have written at least 3 or 4 times as many posts as I have submitted. During the process of writing my post, I have to take a break from 'the problem' in order to sum it up with contextual meaning for the monastery. Often, during this time, I realise my brain's little trick. And often it is something just like your post that lies at the core of my problem. -=( Graq )=-	[reply]

Shouldn't it say "would sort (1, 10, 2) into (1, 2, 10)" And, of course, the other approach is: Try it and see: `>perl -wMstrict -le "my @un_ord = (2, 100, 3, 10, 4, 1); my @n_ord = sort { $a <=> $b } @un_ord; print qq{@n_ord}; my @s_ord = sort { $a cmp $b } @un_ord; print qq{@s_ord}; my @d_ord = sort @un_ord; print qq{@d_ord}; " 1 2 3 4 10 100 1 10 100 2 3 4 1 10 100 2 3 4` [download]	[reply] [d/l]
