-struct CUB_NS_QUALIFIER::FpLimits<bfloat16_t>
+struct __is_extended_floating_point<bfloat16_t> : true_type


question: Can you help me understand where this is used? My mental model of of our custom bfloat16_t and half_t is that we use them to "emulate" the native extended fp types in the absence of those. The reason I am asking is that I would like to make sure we're not promoting these "emulated" wrapper types to be a "real extended fp type" in places where it isn't.

It's used by cuda::is_floating_point and cuda::std::numeric_limits. Adding bfloat16_t here allows __numeric_limits_impl to be chosen internally by cuda::std::numeric_limits. It also makes sure that since cuda::is_floating_point<__nv_bfloat16> is true, cuda::is_floating_point<bfloat16_t> is also true. So in short, it alignes the traits and limits for __nv_bfloat16 and its wrapper type.

The same goes for __half and half_t.
