Hello,

I am dumping a hash table as follows: 

sub myMethod {

...    
    foreach $keyOut (sort {$a <=> $b} keys %hshOut) {
        ...
    }
...
}

The error is as follows:

Argument "" isn't numeric in sort at C:/Perl/site/lib/Foo/A.pm line 163.

The keys are in the format #.#. How do I get rid of this error without changing my keys?

Thank you :)
