in reply to confused: string and number comparison

Why not just do a string equality comparison for both? You won't have the warning, and comparing '0' to 0 will give you the desired outcome.

Update: Just checking the value's truthiness should also suffice. 

my @comparisons = ('0', 0, 1, '', '0 but true', 'abcd');

for (@comparisons) {  
   if ($_) {
      print "keep [$_]\n";
   }
   else {
      print "discard [$_]\n";
   }
}

    No, it won't. OP says that he's looking for cells containing either the single digit 0 or a single space, which is a true value. If he were looking for 0 or an empty string, then just checking truthiness would work, though.

      And that's what I get for not reading the spec thoroughly...
