awk - Print Sum
Hi,

I have an awk command that I am using, and part of it sums COL_9 however when I read the output it is not including decimal places;

Code:
awk '
BEGIN{FS=OFS=","}
NR==1{print;next}
{a[$4";"$7";"$8";"$18]+=$9
c[$4";"$7";"$8";"$18] = $12
d[$4";"$7";"$8";"$18] = $18
}
 END{for(i in a) {split(i,b,";"); print $1, $2, $3, b[1], $5, $6, b[2], b[3], a[i], $10, $11, c[i], $13, $14, $15, $16, $17, d[i]}}' file.csv > file2.csv

Is there a way to make sure this prints decimal places? I need just 2 decimal places?

Thanks for your help.

You need to printf using the adequate format string. print itself won't; man awk:

Print formats numbers using OFMT or "%d" for exact integers.
