What's "normal" rounding??????
One can round with a roof function, or one can round with a sealing function,
or one can round always towards odd numbers, or always even number, or one can
round by adding or subtracting a factor 0,5 to the multiple before rounding,
or one can use a combination of the above, so I am curious about to know what's
normal, and why it is normal then?

Well, I suppose rounding by the dictionary's definition can mean any kind
of approximation to a number of less significant digits, so I see your
point. But by the popular vernacular and by the default precision for any
programming language's "round" function that I've encountered (including
PHP's), the default precision is to round to the nearest integer. Thus, by
both of these modest leaps of assumption, normal rounding to me is rounding
to the nearest integer.

To be a bit philosophical about it, yes. Rounding is always a matter of losing
information (e.g. precision), and you can never tell in what "direction" the
information was lost.
Ex:
The number '2' I now have, was it - to be extreme - it '1,1' (a sealing
function) or was it '2,9' (a floor function) before? You can never really
tell...

Which integer is "nearest" for 1,5? 1 or 2? To round a decimal number is not
as straight forward as it might appear in the first case.
Anybody who happens to know what Kunts Handbook says in this issue?

I agree that most rounding functions probably performs a sealing function
when the less significant decimal is >5 and a floor function when it is <5.
But what is a normal behavior when it is ==5 ???
In the bitter end this choice is up to the API writers own whim, but in most
case I guess (s)he ignore this case, and I would guess that most rounding
function then perform a floor function in the case of ==5 (????).
The point I want to make is this: You'll never know until you tested it!
Because of this I believe it a bit ambiguous to say "normal" since it hardly
can't exist a "normal" way to perform a rounding. Or??
Secondly, because of this "phenomena" some programmers might frequently find
them self having to answers question from customer like:
"Why does we miss $xxxx in this last summary report?".

If it was by the rule we've settled on below, then if you have 2, then the
number you previously had was >=1.5 and < 2.5. :)

1.5 is the only special case.

As far as I know, .5 always gets rounded up, not down. In school we were
taught, "Four to the floor, Five to the sky". :)

I guess. The dictionary defines normal, though, as "Conforming with,
adhering to, or constituting a norm, standard, pattern, level, or type;
typical". So if there is a standard, typical, etc. way that rounding is
done, then you can certainly make a case that there is a normal kind of
rounding. In ALL of my experiences, rounding has been defined as going to
the nearest integer, and rounding UP on .5. And, like I said, all
programming languages I have encountered perform a standard rounding the
same way. That's why we as societies settle on norms -- so we can
communicate without having to resort to academic analyses of every term we
use. :) There's no need to feel the need to one-up everything I say. :)

Shall we settle this argument once and for all?...
The answer is
$value = round($value, 2);
Which I found after a quick look in the manual. Silly me expected the
original poster to have actually searched this far and found there WASN'T a
pre-written function.
Really irritates me that, and I'm sure we'll all agree on that! ;D

Hi folks,
I recently wrote a website that stores session information using PHP 4.0.6
on win2k, with php as a module in apache.
However, I've just moved the same site across to another machine again using
win2k, with php as a module in apache but this time with PHP 4.1.2 and now
the session information does not seem to be stored.
The session file gets created in the session directory and the array
$_SESSION exists and stores my data within a page, but the information
doesn't get stored in the session file.
I've checked the php.ini files between versions and the session information
is the same.
Does anyone know whether there's an issue with session on 4.1.2, or does the
session stuff work differently in 4.1.x?
thanks in advance,

Hey Martin,
I've got the same problem with php4.1.2 as an apache module.
As far as i could find out the whole thing depends on the php4ts.dll (using
win2k).
Probably it's a bug in 4.1.2?

check bug fix 16435 for php in the bug database. I've encountered this
prob and it's a recurring theme but it's fixed in the Release Candidate
1 and 2 for php 4.2.....have to patch the php4ts.dll and php4apache.dll
with these new ones in the RC.
bug and fix: http://bugs.php.net/bug.php?id=16435
At http://www.php.net/~derick/ you can find RC2.

You've to install one od the two dll (fdfacx.dll and fdftk.dll) included in the
adobe's package. Use "regsvr32 fdfacx.dll"
Now you can use the toolkit...why don't you use the pdflib extension?
