Can we get a FAQ entry on the topic? Bonus points for an example user implementation.
Thanks for your answer and for a great library!

Hi Jarom, We did originally plan to add support for complex types in HDF5-1.10. However, after the issue was examined closely, we decided to wait until we had a well-defined scope of what it means to add support for complex types within the library. The issue is still open but not assigned to be fixed in a specific release. -Barbara From: Hdf-forum [mailto:[email protected]] On Behalf Of Nelson, Jarom Sent: Thursday, February 09, 2017 10:32 AM To: [email protected]<mailto:[email protected]> Subject: [Hdf-forum] Complex numbers (1.10.x update?) At what point (if any?) will HDF5 support a complex floating point datatype (i.e. pair of real and imaginary floating point numbers) "out-of-the-box"? This is probably something that comes up frequently, but I haven't found the current status of the question. Searching the archives and the documentation, it seems that a complex floating point data type was at one point planned for the 1.10 release, however, I don't see anything about continuation of that plan in the documentation. Ref: these two threads from 2010 https://lists.hdfgroup.org/pipermail/hdf-forum_lists.hdfgroup.org/2010-December/004011.html https://lists.hdfgroup.org/pipermail/hdf-forum_lists.hdfgroup.org/2010-April/003049.html Perhaps the answer can be implied from this point in that thread: To be fair, because there's no one-size-fits-all complex number solution outside Fortran, a one-size-fits-all cross-language HDF5 helper method to define a complex type would be difficult to get right. Not technically difficult, just socially difficult. - Rhys Also, this seems like a likely topic for a FAQ. (There's one there for boolean datatype) Jarom Nelson, LLNL
