Hi Greg, Great that you’re still using PDL! And thank you for PDL::LinearAlgebra, which you may have seen has been updated for “native complex”.
There isn’t yet a great way to get at NaN/Inf, but I am intending to make core functions that return those, since they are available at the C level in order to implement various parts of PDL::Bad. If someone wants to beat me to it with a PR, please say so here (so we don’t both work on it at the same time) and go ahead! I think that PDL::Bad::nan and PDL::Core::inf (due to where they are used, but perhaps both in PDL::Core) would be the place to put them. In the meantime, “asin(2)” returns NaN, and pdl(‘inf’) returns Inf (via “-pdl(0)->log”).

Standards have changed. Do you happen to know how to create these?
