Hello,
I have to write a function to input a Label and a number, and output a line as the following format:
Column 1 to 30: field label, left justified.
Column 31 to 45: A number, right justified.
The middle is padded with space. May I know how can I achieve this? (I don't know how to count... (3 Replies)
I need to right-pad with zeros a string by using (s)printf.
I looked up the manual and tried with
printf("%-19s", buffer);
which right-pad the string with spaces. So I tried
printf("%019s", buffer);
which left-pad the string with zeros. So I tried both
printf("%-019s", buffer);... (9 Replies)
I have number/strings like below
input =23412133
output = 234121330000 (depends on the number give at runtime)
i need to padd zeros based on runtime input . i tried below
printf ' %d%04d\n', "23412133";
But the precision 4 is static here how can i pass this as runtime input.
i am... (11 Replies)

CheckDigits::M10_002 - compute check digits for CINS (US), SIREN (FR), SIRET (FR)
SYNOPSIS
use Algorithm::CheckDigits;
$siret = CheckDigits('siret');
if ($siret->is_valid('73282932000074')) {
# do something
}
$cn = $siret->complete('7328293200007');
# $cn = '73282932000074'
$cd = $siret->checkdigit('73282932000074');
# $cd = '4'
$bn = $siret->basenumber('73282932000074');
# $bn = '7328293200007'
DESCRIPTION
ALGORITHM
1. Beginning right all numbers are weighted alternatively 1 and 2.
2. The total of the digits of all products is computed.
3. The sum of step 3 ist taken modulo 10.
4. The check digit is the difference between 10 and the number from step 3 taken modulo 10.
METHODS
is_valid($number)
Returns true only if $number consists solely of numbers and the last digit is a valid check digit according to the algorithm given
above.
Returns false otherwise,
complete($number)
The check digit for $number is computed and concatenated to the end of $number.
Returns the complete number with check digit or '' if $number does not consist solely of digits and spaces.
basenumber($number)
Returns the basenumber of $number if $number has a valid check digit.
Return '' otherwise.
checkdigit($number)
Returns the checkdigit of $number if $number has a valid check digit.
Return '' otherwise.
EXPORT
None by default.
