Re: formating variables again...
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 subsititution.

Subject: formating variables again...
Hi,
I have a variable $var = 34.5678
If I
printf (%.2f, $var);
Then $var = 34.56
Is there a way for me to format $var to became 34,56 instead of 34.56 ???
Thanks,
Wagner.

Re: $variable manipulation question
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 reverse the list
order so it's normal again.'
$input = 1234;
while($input ne undef){
push(@front_chars,chop($input));
}
@front_chars = reverse @front_chars;

Re: Replacing carriage returns in a variable
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 advances to the next line, and used without a carriage return, enabled e.e.cummings to write his non-stop paragraphing. - Roger - - Original Message - From: Guy Tubbs [EMAIL PROTECTED] To: Roger C Haslock [EMAIL PROTECTED]; [EMAIL PROTECTED]; [EMAIL PROTECTED] Sent: Tuesday, October 02, 2001 9:52 AM Subject: RE: Replacing carriage returns in a variable Thanks for your replies.

How did that help you? Now you have an array of individual
characters, gotten the hard way. Using split() is the way
to do this (see perldoc -f split):
@chars = split //, $input;
To print this list out with spaces between, you can:
$ = ' '; # this is the default
print @chars; # double quotes required here
or
print join ' ', @chars;
The split and join can be combined to elminate the intermediate
array:
print join ' ', split //, $input;

Re: $variable manipulation question
How did that help you? Now you have an array of individual
characters, gotten the hard way.
Originally I was aiming to space each character apart so I could use a space
' ' as the delimiting character when I brought them into an array (to be
analyzed character by character by other following routines).
ie. $input = '12345' - $input = '1 2 3 4 5'
so I could use:
@chars = split(/ /,$input);
to get the individual characters into their own array items.
Your:
@chars = split //, $input;
Does this all in one bang which is great! Thanks!
Brian's
print join ' ', split //, $input;
doesn't actually change $input's content however.
