Need help for awk command

Hi

I have a column which contains values like
000000000035.25600

I want the output as
Code:
00000000000035.256
 
i.e Two zero'z should be appended at the beginning and removed from the end

Could you please help me with a command for this. I want to modify all the records for this column in the file. The column number is 10th column in the file

Do all values in 10th column contain exactly 2 zeroes at the end?

Try:
Code:
$10=sprintf("%018.3f",$10)

By using Scrutinizer's format in a awk command like:

Code:
awk '{$10=sprintf("%018.3f",$10)}1' infile

That assumes that the columns are space separated.

Edit: Ooops. Scrutinizer is lightning fast and gets up early on a saterday morning ^_^
