I guess I could raise that at MIOpen upstream. In any case, the package will remain in experimental until MIOpen itself is ready. >> This is needed by MIOpen, which is also in the process of being >> packaged. Best, Christian

Bug#1049960: ITP: half -- C++ library for half precision floating point arithmetics
Package: wnpp Severity: wishlist Owner: Christian Kastner X-Debbugs-Cc: debian-de...@lists.debian.org, debian...@lists.debian.org * Package name: half Version : 2.2.0 Upstream Author : Christian Rau * URL : https://sourceforge.net/projects/half/ * License : MIT Programming Lang: C++ Description : C++ library for half precision floating point arithmetics This is a C++ header-only library to provide an IEEE-754 conformant half-precision floating point type along with corresponding arithmetic operators, type conversions and common mathematical functions. It aims for both efficiency and ease of use, trying to accurately mimic the behaviour of the builtin floating point types at the best performance possible. It automatically uses and provides C++11 features when possible, but stays completely C++98-compatible when neccessary. This is needed by MIOpen, which is also in the process of being packaged. This will be maintained by the Debian ROCm Team.
