NAME
       PDL::Bad - PDL does not process bad values

DESCRIPTION
       PDL has been compiled with WITH_BADVAL either 0 or undef,
       so it does not contain any bad-value support code.  Actu-
       ally, a number of methods are defined, but they are only
       placeholders to make writing other code, that has to han-
       dle WITH_BADVAL being true or false, easier.

       Implementation details are given in PDL::BadValues.

SYNOPSIS
        use PDL::Bad;
        print "\nBad value support in PDL is turned " .
            $PDL::Bad::Status ? "on" : "off" . ".\n";

        Bad value support in PDL is turned off.
