What was the plan for LIAW this year ? IIRC some stuff were pointed otu last eyar as potential contenders.
Is the list of potential contenders available somewhere?
I don't know. Hartmut? Jeff?
Proto would be used for creating all arithmetic operations since the return type of a+b could be different from the type of either a or b. A bonus would involve getting the fixed-point data type to play well with std::complex (and, yes, I am aware that std::complex is not designed to work with anything other than double and float, and will require specialization in the std namespace).
Well, isnt having a boost::complex data type be of interest too ?
It would be of interest to me but I am afraid that too much bike-shedding might ensue. Complex numbers are extremely straightforward with multiple sets of equivalent perfectly internally consistent minimal interfaces; in such cases, personal preferences decide the interface, more or less. See N1589 for examples.
If there is sufficient interest, I could even provide a starting point with +,-,* implemented; / would take more time. The design above is intended as a starting point for discussion and I am most definitely not wedded to it. I am a tyro when it comes to proto, and hence would need someone with more proto expertise to guide the discussion.
I can help on this point
Are you volunteering/proposing to run the LIAW session? What is the standard procedure for running the LIAW session?
I know that in past years, Jeff has run the LIAW session. I expect this year would be no exception, but it would certainly be good to have a proto expert on hand. Joel would be perfect for that. I just want to say I think a proto-based fixed-point number library is a really fun idea for a LIAW project. Meaty and doable.
