Folks,
Is there a simple way to replace one digit by two digit using sed.
Example,
mydigit1918_2006_8_8_lag1.csv should be

echo mydigit1989_2006_8_8_lag1.csv|sed 's/]/0]/'
Thank you, (5 Replies)

I want to write/print a number through a shell script up to its last significant digit (LSD) after the decimal point.
Say,
x=10.00056000000000000
I want to print x as x=10.00056.
Note that x can be any thing so I cannot know the position of the LSD always.
Thanks. (16 Replies)

CheckDigits::MXX_005(3pm) User Contributed Perl Documentation CheckDigits::MXX_005(3pm)NAME
CheckDigits::MXX_005 - compute check digits for ESR9 (CH)
SYNOPSIS
use Algorithm::CheckDigits;
$esr = CheckDigits('esr9');
if ($esr->is_valid('123456786')) {
# do something
}
$cn = $esr->complete('12345678');
# $cn = '123456786'
$cd = $esr->checkdigit('123456786');
# $cd = '6'
$bn = $esr->basenumber('123456786');
# $bn = '12345678'
DESCRIPTION
ALGORITHM
1. Digits are processed left to right. For the first digit applies the balance is 0.
2. The new balance is taken from the balance table according to the current balance (row) and the digit (column).
3. The check digit is the difference from the last balance to 10 taken modulo 10.
METHODS
is_valid($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.
