Olivier<p>I've been working with C++ numerical/scientific software for over 10 years, and one of my biggest grief is mishandling of numerical conversions. The <a href="https://en.cppreference.com/w/cpp/language/implicit_conversion" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">en.cppreference.com/w/cpp/lang</span><span class="invisible">uage/implicit_conversion</span></a> rules are confusing at best, and have undefined outcomes in too many cases. And the fact that static_cast will simply hush compiler warnings is both misleading and dangerous. Lastly, the std functions are an inconsistently named mess: round has lround, but not ceil, floor or trunc. Then there's the 27 easy flavours of rint and nearbyint that are almost the same except exceptions.</p><p>There have been some improvements recently though.</p><p>The cpp core guidelines have a gsl narrow that throws a catchable exception. However that's a very limited and limiting use case. Then there's gsl narrow_cast which is nothing more than a FIXME ("you asked for it," as they say).</p><p>C++26 is finally introducing <a href="https://en.cppreference.com/w/cpp/numeric/saturate_cast" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">en.cppreference.com/w/cpp/nume</span><span class="invisible">ric/saturate_cast</span></a> to convert between integer types without implicit truncation (or undefined behaviour).</p><p>I hope the C++ standards committee acknowledges and addresses this issue in a clean consistent way once and for all.</p><p><a href="https://sunny.garden/tags/cpp" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>cpp</span></a> <a href="https://sunny.garden/tags/cplusplus" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>cplusplus</span></a> <a href="https://sunny.garden/tags/numerical" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>numerical</span></a> <a href="https://sunny.garden/tags/software" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>software</span></a> <a href="https://sunny.garden/tags/softwaredevelopment" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>softwaredevelopment</span></a></p>
