Huh :eek: what kind of answer is this?

There are a lot of threads regarding floating arithmetic with shell scripting, search for floating arithmetic.

sum=`expr $a + $sum | bc`

Hi ,

For division,, you can use like this...(using awk)

 echo "test"|awk -v var1=3.3 -v var2=3 '{print var1 / var2}'

Thanks
