in reply to Any improvement over the code possible??

Add input checking. If I input "2" and "F", the code tells me the average is 1. That is probably not how you want the code to behave. Look at Scalar::Util::looks_like_number.

Thanks for reply :)

I tried out this code.. but its not giving what I expected. Is it how it works??

#!/perl/bin
use v5.14;
use Scalar::Util;

say &Scalar::Util::looks_like_number('2');

I haven't studied till packages and modules.. So, don't know exactly how to use them..

its not giving what I expected

You need to tell us what you expect it to do. Or read the doc I linked to:

looks_like_number EXPR

Returns true if perl thinks EXPR is a number.

Super Search is another way to find answers and see code examples.

If I write like this: -

say looks_like_number '2'

It should return false as I understand.. but its not printing anything

Neither in the case I give there a number 2
