I would have done it like this.
$var = 34.5678;
$var=~/((\d+).(\d{0,2}))/;
$var = $1;
$var=~s/\./,/sg;
printf ( The formated value is : $var);
---OUTPUT
The formated value is : 34.56
Well there may be better and more straigth forward ways, I was just trying
to get used to Patterns and
Yeup ! The the TYPE declaration is very important !.
We tend to ignore such things when we use MS platforms...:-(
Thanks for correcting me Michael .

Thanks for your replies.
It does insert another character, but keeps the return too.
I have tried:
$text =~ s/\n/br/g;
and
$text =~ s/\r/br/g;
but it does the same thing, i.e. I get:
Line1br
Line2
What I need is:
Line1brLine2
Do you know how to get rid of the returns altogether?
Hi all,
I'm trying to get a string (held in a variable) to have all it's characters
spaced apart by a ' ' space.
ie. $input's content changes from '1234' to '1 2 3 4'
Is there some way to do this?
cheers,

I found a solution not long after using a loop of sorts. (and killed two
birds with one stone, as my next step was to put each item (space delimited)
into an array).
I made a loop saying, 'as long as $input still has characters in it, put
each one (one at a time) into the @front_chars array, then

Yes this is infact helped me.

Note: this code only replaces carriage returns, not line feeds.
Remember an ancient typewriter. The carriage return returns the carriage to
the beginning of the line, but does not advance to the next line. This
enables the typist to overstrike, underline, or embolden characters. The
linefeed

That looks like a very compact way of doing it, Brian- is it possible to get
a bit of a rundown of how it works?

Odd. Here's the code snippet I ran right at the command-line:
$ perl
$text = line1\nline2\n;

Hi,
I have a variable $var = 34.5678
If I
printf (%.2f, $var);
Then $var = 34.56
Is there
If you are sure its a string, maybe you can use 'unpack', and then 'join'.

How did that help you? Now you have an array of individual

Has anyone ever gotten this error from perl? How do I resolve it?
panic: frexp at IWfacschd.cgi.exp line 366.
line 366: $fte = sprintf(%2.4f, $fte);
$fte is a returned number from a database.
frexp is apparently a library that allows the printf('%f') to work but has
failed.

Hey everybody,
I've got a PostFix mail server set up that's working fine. However, in some
cases we want to generate output files and attach them to an e-mail instead
of just dumping the HTML data in text form into an e-mail. Anybody know how
I can do that?
Thanks in advance.

Hi all,
I'm trying to get this string (example):
$all_codes = '4c1 4- 4c2 4-8b1 8g1';
in to an array (@codes), using it's whitespace as the delimiter.
ie. @codes = split(/ /,$all_codes);
but I keep getting extra whitespace elements picked up into the array...:
'4c1,4-,4c2,4-, ,8b1,8g1'
Hi Shannon,
Very close. You are allowed to use a pattern in a split.
my @codes = split(/\s+/,$all_codes);
Should give you what you want. This will split the string on 1 or more spaces.
Look at 'perldoc -f split' for more information.
Cheers,
Kevin
