# 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. Actually, a number of methods are defined, but they are only placeholders to make writing other code, that has to handle WITH_BADVAL being true or false, easier.

Implementation details are given in the PDL::BadValues manpage.

# 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.

# VARIABLES

There are currently two variables that this module defines which may be of use.

$PDL::Bad::Status
  Set to 0

$PDL::Bad::UseNaN
  Set to 0
