Adding up a list of numbers in KSH

[AdamCoombs]

Hello...

I need to be able to total up a column of numbers..
prices to be precise!

29.99
22.99
24.99
etc etc

dont care how we do it, i can pull the numbers out and put them in their own file for the adding up bit...!
HELP PLEASE!
cheers
Adam

Are you always going to have two decimal places?

 

[AdamCoombs]

yup, there prices...
if its just 23 pounds then i can force the user to enter 23.00 if need be!

I've got something that adds whole numbers, but ignores the numbers right of the decimal. I'm trying to figure a way to multiply the lines by 100, then add them and then divide the result by 100.

Here is what I have used successfully with files (with an extension of .num) that have lists of whole numbers:

for filename in *.num
do
typeset -i i
i=0
while read -r j
do
i=i+j
done < ${filename}
echo $i > ${filename}.total
done

I'll try to dig some more.

awk '{sum+=$1} END {print sum}' < $filename > $filename.total

you star..
thanks...
