in reply to Argument "" Isn't numeric in numeric eq (==)

You could just disable warnings, but why not say what you intend?

If you want blank entries to be 0, just make them so: 

# Consider all blank entries to be 0.
foreach (@f) {
    $_ = 0 unless length $_;
}

After that, all your ""'s become zeros, and == will behave just fine.
