So you have ascertained that the error happens because you enter that block of code but $array[4] contains a value that Perl interprets as zero.

Maybe you don't want to enter that block if $array[4] contains a value that Perl interprets as zero? Maybe you want to prevent processing invalid lines that leave invalid values in @F?

You have not shown examples of valid and problematic lines, so we can only guess and trace the path of execution backwards from where the error happens. If you tell us what you want to avoid, or for what kind of lines the error happens, maybe we can better find a solution with you.

Maybe you want to skip processing empty lines?
