As far as I know, HDF5 does not support 16 bit floating point. If the goal is to save space, then one approach is to create a special filter that converts between 16 bit in the file and 32 bit in memory. > Organization: EUMETSAT > Package Version: > Operating System: > Hardware: > Description of problem: This is not really a request, it is just curiosity. > > Regarding floating-points data formats, currently netCDF implements the > standard single and double precision. > > I am wondering if netCDF considered the implementation of the half-precision > floating point format (aka 2-byte floating point, binary16, etc). > https://en.wikipedia.org/wiki/Half-precision_floating-point_format > > This data type has a resolution that could be good enough for many purposes, > and at the same time it keeps simplicity (no need to bother with 2-byte > integers and "add_offset" and "scale_factor" attributes; or no need to define > single precision format together with the "significant number of digits" and > compress). > > Perhaps the key point is whether this is already implemented in HDF5, and > this is not clear to me. > > Anyway, my question is: Is half-precision floating point data format > considered for implementation in netCDF? > > Thank you. > > =Dennis Heimbigner Unidata Ticket Details =================== Ticket ID: IST-525664 Department: Support netCDF Priority: Normal Status: Open =================== NOTE: All email exchanges with Unidata User Support are recorded in the Unidata inquiry tracking system and then made publicly available through the web.
