awk sum of all columns needs to print exact amount
Hi
I have attached txt file as input,
and i'm able to calculate sum of columns at the end but the format of sum is not coming up right.

Code:
awk -F"," '{for (i=4;i<=NF;i++) sum[i]+=$i}{print}; END { sum[1]="Total:"; for (i=1;i<=NF;i++) {printf  sum[i] ","} print "\n"}' input.txt

check the o/p file, at the Total: line I need to print exact sum of each columns, not 129102+E08 etc.

I even tried to printf "%10.4f" and it's still not working.
can anyone suggests how to print sum of columns with exact amount...

Convert this txt to Excel for better viewing....
