Hello again.
I'm trying to use BC to calculate some numbers in a shell script.
I want to have the numbers rounded off to 1 decimal place.
for example:
initsize=1566720
zipsize=4733
I'm trying to get the ratio between them. the equation is:
(($initsize-$zipsize)/$initsize)*100

Hi,
Can any one help me in finding a solution for rounding off to 2 decimal places.
I am using the following code:
VAR1=.01292105263157894736
VAR2=`echo "scale=2; $VAR1 * 100" | bc -l`
The result I 'm getting is

CheckDigits::M23_002(3pm) User Contributed Perl Documentation CheckDigits::M23_002(3pm)NAME
CheckDigits::M23_002 - compute check digits for VAT Registration Number (IE)
SYNOPSIS
use Algorithm::CheckDigits;
$dni = CheckDigits('ustid_ie');
if ($dni->is_valid('8473625E')) {
# do something
}
$cn = $dni->complete('8473625');
# $cn = '8473625E'
$cd = $dni->checkdigit('8473625E');
# $cd = 'E'
$bn = $dni->basenumber('8473625E');
# $bn = '8473625'
DESCRIPTION
ALGORITHM
1. Beginning right all digits are weighted with their position in the number (i.e. the number left from the check digit is multiplied with
2, the next with 3 and so on).
2. All products are added.
3. The check digit is the sum from step 2 modulo 23. This number is expressed as the corresponding letter from the alphabet where A-V
correspond to 1-22 and W stands for check digit 0.
METHODS
is_valid($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.
