Sorry, we were discussing inf, not NaN... Then constexpr double my_inf = std::numeric_limits<double>::infinity(); If the C++ impl supports ISO/IEC 60559 (an alias of IEEE 754), it will produce a positive infinity. Otherwise the compilation will fail. -- Xi Ruoyao <xry...@mengyan1223.wang> School of Aerospace Science and Technology, Xidian University
