I have some code that looks like this: if ( int( $level ) == 1 ) { push @testList, @originalTopPagePlusFlack; }
When it runs with an empty string in $level, (using strict) I get this warning: ---------------- Argument "" isn't numeric in int at autohits.pl line 352 (#1) (W numeric) The indicated string was fed as an argument to an operator that expected a numeric value instead. If you're fortunate the message will identify which operator was so unfortunate. Argument "" isn't numeric in numeric ne (!=) at autohits.pl line 352 (#1) ---------------- I've tried using index() and an RE instead of the numeric compare, but those give me nearly the same warning. (??) So I am wondering how to get at a value that may be either numeric or an empty string. Thought of using a subroutine, but then I think the subroutine is going to have the same problem if I try to generalize to handle non-empty strings that don't convert. I can simply skip generalizing, but I am wondering if there is something similar to php's is_numeric() (or whatever that was). Any suggestions? -- Joel Rees <[EMAIL PROTECTED]>
