floating point number handling in shell script 1

[inunix]

Here is my input..
eg:
X=`cat abc|wc -l`
Y=`ls *.*|wc -l`
when i divide X/Y, sometime I'm getting results as 0.
I need the output in 2 decimal paces like 0.22 or whatever.

How do achieve this in shell scripts.?

Thanks in advance

First, how are you doing it currently?

Look at

man expr

Try something like this:

echo "$X" "$Y" | awk '{printf "%.2f\n",$1/$2}'

Hope This Help
