That would be more valuable as a separate library. It is good to read this discussion. Historically, it all went like this... When we started <boost/cstdfloat.hpp>, we wereinterested in specifying floating-point types havingfixed-widths. This proposal was abandoned in the2013 timeframe, but recently picked up and broughtinto C++23 with some new stuff. Around that time, we also "invented" Multiprecision,which came into Boost 1.53, basically with the numberbackend and cpp_dec_float only. We went on(with lots and lots of work primiarly by John) toadd several backends to Multiprecision, one ofthem being Multiprecision's float128 backend. So indeed, we have two 128 bit floats hangingaround, yet form some platforms such as thepopular MSVC, we have zero 128-bit floatimplementations. Writing a uniform, cross-platform implementationcombined with aliases and/or seamless use inMultiprecision is, I believe, something of interestto us all. But i believe we need some specifyingwork and a few trial implementations in order tosee how all of this should fit in together nicelain a post C++23 domain. This is good discussion and I think we will followup on it.

Boost docs
by Peter Turcan 11 Apr '23

11 Apr '23

Hi, This week I joined CppAlliance as a technical writer - just introducing myself here! I am pumped to be writing some C++ code after several years hiatus. The last major project I wrote in C++ was a wargame that would cope with battle data from either the Napoleonic wars, or the American Civil War, and was called Battalia. It is still around in archive sites such as: https://archive.org/details/wargamer-depot_battalia Mostly I write developer documentation and tutorials. The work I enjoyed the most was writing the SDK for Microsoft Flight Simulator (and taught myself instrument flying in the process), the User Guides and SDK for WorldWide Telescope (an astronomy viewing program that involved working with NASA on Mars imagery data), and writing a range of developer tutorials for Azure IoT, Azure Search and Azure Maps. I was the main writer at Microsoft for the DirectX 12 documentation - though that was a brutally tough SDK to actually work with. Most developers stuck with DirectX 11 - not sure where Microsoft is now on its graphics APIs. At CppAlliance I hope to add value to the documentation on the libraries where I can - perhaps adding examples, better navigation, and more complete descriptions of parameters, edge-cases, errors - the usual suspects that are often missing from documentation but are sorely needed by developers. Also, I plan on getting hardcore with the introductions to each library. The question that should be answered in introductions to any library (or any SDK) is the "why" question. Why should I be interested in this library? What is the problem that I have that the library is solving? This is often missing. A typical introduction might answer the "What" question - such as "this particular piece of software converts A into B", and the "How" question (what tools and setup is needed), but avoids the why question: "why should I be interested in converting A into B". The answer might be: "this library converts A into B to provide your data with an additional level of security, when the data is communicated over the internet." By answering the why question, any developer will know immediately whether to continue reading, or look elsewhere. Another aspect of documentation to look at is style. For API reference type documentation (interfaces, functions, parameters), mostly a neutral style works well - just say exactly what is going on. For guide or more conceptual material, perhaps a chattier style is more appropriate - short sharp sentences, some wit and wisdom, less formality - like talking to a knowledgeable buddy. You probably have some great ideas too on adding value to the existing Boost documentation - happy to hear any and all feedback! - best Peter

about boost::math
by Gero Peterhoff 11 Apr '23

11 Apr '23

a) __STDCPP_FLOAT80_T__ With C++23 we get std::floatN_t-types, which are displayed by the macros __STDCPP_FLOATn_T__. However I miss __STDCPP_FLOAT80_T__, which has its justification/relevance. One could retrofit this #if defined(BOOST_CSTDFLOAT_FLOAT80_NATIVE_TYPE) #define __STDCPP_FLOAT80_T__ namespace std { using float80_t = boost::float80_t; } #endif Would this be useful/wanted like this? b) complex-functions Since C++11 there are the functions abs, asin/h, acos/h, atan/h. These are also defined in boost/math/complex.hpp. But now with 1.82 boost::math is based on C++14, which makes these manual implementations obsolete -> boost/math/complex.hpp can be removed. c) constexpr I want to upgrade some functions in boost::math. How should/can I handle constexpr there? My problem is: - in gcc almost all math functions are constexpr - otherwise only some math functions with C++23 are constexpr Now it would be suboptimal not to use constexpr just because it is currently not in the standard. - If I don't define the additional functions as constexpr or stick strictly to the standard, performance might be wasted, which I don't want. - Can I simply define the additional functions with constexpr/BOOST_CXX14_CONSTEXPR? In case of an error there will be the standard-error "not constexpr". d) implementation In https://www.boost.org/doc/libs/1_82_0_beta1/libs/math/doc/html/math_toolkit… you describe how to implement a new math function. Is this still up to date or is it necessary for simple functions? E.g. cot -> 1/tan. thx Gero
