[rrd-users] no NaN values in perl?

I'm new to this list and fairly new to using rrdtool.
I found it quite useful to be able to store undefined 'NaN'
values beneath numeric values in the rrd ...
(eg. to differentiate between system offline and 0-value)
Works great when using rrdtool as a standalone, however, when
using RRDs::fetch in perl, all NaN values get converted into
'0' when fetching values from the RRDB.
Why? Am I doing anything wrong?
I've tried to search the archives for hints and found many
people complaining about NaN - however, I do want to get them.
My apologies if this has been asked before - please point me
to some documentation about this - if there's any.
Many thanks for your help.
