To get a single SV out of an ndarray, use $pdl->at($offset1, ...). That SV will have the appropriate numerical info available, be it NV, IV or UV.

By the way, this is as you have marioroy has been doing with some of your test scripts, including looping over large ndarrays one element at a time. That made those scripts go impressively slower with PDL than the other versions. PDL has a function to output ndarrays in text column format: https://metacpan.org/pod/PDL::IO::Misc#wcols.
