Shell Programming and Scripting

Hi everyone, I am having some problems with my scripts so I hope you could help me.
I am trying to store the result of a division in a variable in tcshell but I have the problem that if:

For example, dividing 2/100 the result is 0.02 but if I store that I have "0".

How can I have 0.02 stored?

Thank you, and sorry for my English

Ok, I have to use bc.
But, I do not want to put the scale, I want it shows the number until it finds a decimal number.

Example: 2/100 = 0.2000000
I only want it shows 0.2

And the same with all the divisions, any idea? thank you

Could you give me an example of how to use awk?

You cannot keep a float value in a shell variable. For calculations yeilding float values, you can use tools such as awk / bc. Howver, the float results can be stored only as a string in shell variable.

In ksh (ksh93) you can.

Well, I want to show the value in the shell

Code:

$  echo 2 100 | awk '{print $1 / $2}'
0.02

$  X=$(echo 2 100 | awk '{print $1 / $2}')
$  echo $X
0.02
