Also taking into account versioning. + +Status reminder: +- Thanks to Maciej, we became aware that there is a very promising project which has been proposed for C++ 29 standardisation, https://github.com/mpusz/mp-units, so support units and constants in C++. We think it’s the right approach to investigate this library and see if it would be suitable for our needs. If it is on the road to an stdlib inclusion then that makes it much more future proof that anything we would write ourselves. +- The units support looks very well written and robust, and there are already some HEP relevant constants in the library: https://github.com/mpusz/mp-units/blob/master/src/systems/include/mp-units/systems/hep.h. There is a also a lot of documentation about the motivations and a review of existing solutions and their limitations (e.g., Boost::Units). +- So we’d like to proceed to try and both use this library, extend it to the kind of PDG quantities that we would want. + +Please let Graeme know if you'd like to be kept in the loop. + +### Next Meeting + +The next coordination meeting will be October 9th, , Stefan will chair. + +### Chair This Meeting 👇 + +Please [sign up](https://docs.google.com/spreadsheets/d/1Z1Z4payCpieOLiVFcC6y9j-KCj71u6xX232LHUgIHfI/edit) for chairing a future coordination meeting.
