Decimal to BCD (Binary Coded Decimal)
Use and complete the template provided. The entire template must be completed. If you don't, your post may be deleted!
1. The problem statement, all variables and given/known data:
Design an algorithm that accepts an input a decimal number and converts it into BCD (Binary Coded Decimal) representation. Also, draw its Flow Chart.
2. Relevant commands, code, scripts, algorithms:
UNIX
3. The attempts at a solution (include all code and scripts):
1:[enter the number]
read n
2:[find the length]
leng=length(n)
a=0
3:[perform the conversion]
for i=0 to leng-1
n1=n1%2[to take the right most digit]
for j=0 to 3
n2=n1%2[to take the reminder]
ans[a]=n2
a++
n1=n1/2
end for
n=n/10[to take the number except the right digit]
end for
[print the number]
fori=a-1 to 0
print ans[i]

algorithm::checkdigits::mbase_002
CheckDigits::MBase_002(3pm) User Contributed Perl Documentation CheckDigits::MBase_002(3pm)
NAME
CheckDigits::MBase_002 - compute check digits for blood bags (DE), BZUe (DE), VAT Registration Number (DE)
SYNOPSIS
use Algorithm::CheckDigits;
$bb = CheckDigits('blutbeutel');
if ($bb->is_valid('2761011234567893')) {
# do something
}
$cn = $bb->complete('276101123456789');
# $cn = '2761011234567893'
$cd = $bb->checkdigit('2761011234567893');
# $cd = '3'
$bn = $bb->basenumber('2761011234567893');
# $bn = '276101123456789';
DESCRIPTION
ALGORITHM
1. Start with values P = 10, S = 0.
2. Beginning left you do the following for all digits
1. S = (P + digit) modulo 10
2. If S is 0 then S = 10.
3. P = (2 * S) modulo 11
3. The check digit is (11 - P) modulo 10.
METHODS
is_valid($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.
