Bad

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 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.

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
