Pad Zeros at the end

I have number/strings like below
Code:
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 using this is shell script

Adding zeros to the end of a number changes its value, so printf isn't set up to do that.

Could you be more clear on your requirements, do you want to know how to use arguments within a script/function $1 $2... or are you wondering how to add orders of magnitude to an integer?

how many zeroes you need to add at the end..?
if it is 4 always then simply multiply that no. by 10000 and then print.

i have shell script
Code:
 
While <read file>
do
ecode=`echo $line | cut -d"|" -f4`
length=`echo $line | cut -d"|" -f5`
 
example ecode will have 
34628
23492759
523489573
156232
123414
1233
 
length=10
 
output
3462800000
2349275900
 
i need to append zeros at the end of the each based on the length field

go with this ..
Code:
$ z=10
$ echo "1234 * 10^$z" | bc
12340000000000

try this:

Code:
$tmp=$ecode;
$count=0;

while($tmp>0)
{         $tmp=$tmp/10; $count++;      }

$output=$ecode*10^($length-$count);

print $output;
