How to get decimal values ?
Hi All,

In my script I've written like this-

Code:
c=$( expr 100 / 3);echo $c

The output coming is 33. but I want to see 33.33, decimal values too. How to get that?

Thanks,
Naresh

Try this,
Code:
c=$(echo "scale=2;100/3" |bc);echo $c

Sorry previous post was not there when I checked.
