Try like this,

sum=$(print "scale = 2; $up/$down" | bc)

try

$ sum=`expr $up / $down`
$ echo $sum

Try this
div=$(($x / $y))

This will store the result of division in the div variable.

Regards,
Rahul.

You will not get decimal points with this solution if the $down value is greater than $up value.
