/**
* \defgroup CUDA_MATH_INTRINSIC_BFLOAT16 Bfloat16 Precision Intrinsics
* This section describes nv_bfloat16 precision intrinsic functions.
* To use these functions, include the header file \p cuda_bf16.h in your program.
* All of the functions defined here are available in device code.
* Some of the functions are also available to host compilers, please
* refer to respective functions' documentation for details.
*
* NOTE: Aggressive floating-point optimizations performed by host or device
* compilers may affect numeric behavior of the functions implemented in this
* header. Specific examples are:
* - hsin(__nv_bfloat16);
* - hcos(__nv_bfloat16);
* - h2sin(__nv_bfloat162);
* - h2cos(__nv_bfloat162);
*
* The following macros are available to help users selectively enable/disable
* various definitions present in the header file:
* - \p CUDA_NO_BFLOAT16 - If defined, this macro will prevent the definition of
* additional type aliases in the global namespace, helping to avoid potential
* conflicts with symbols defined in the user program.
* - \p __CUDA_NO_BFLOAT16_CONVERSIONS__ - If defined, this macro will prevent
* the use of the C++ type conversions (converting constructors and conversion
* operators) that are common for built-in floating-point types, but may be
* undesirable for \p __nv_bfloat16 which is essentially a user-defined type.
* - \p __CUDA_NO_BFLOAT16_OPERATORS__ and \p __CUDA_NO_BFLOAT162_OPERATORS__ -
* If defined, these macros will prevent the inadvertent use of usual arithmetic
* and comparison operators. This enforces the storage-only type semantics and
* prevents C++ style computations on \p __nv_bfloat16 and \p __nv_bfloat162 types.
