Description
... but it isn't:
contexpr qfloat16 f16 = 42.f; // ERROR: not a constant expression
I realize that the conversion depends on some tables, but if consteval or std::is_constant_evaluated() may allow to have an alternative implementation that is constexpr. Maybe an algorithmic one that would be too slow for runtime?
