All wrapped libdevice functions are listed in this section. All functions in libdevice are wrapped, with the exception of __nv_nan and __nv_nanf. These functions return a representation of a quiet NaN, but the argument they take (a pointer to an object specifying the representation) is undocumented, and follows an unusual form compared to the rest of libdevice - it is not an output like every other pointer argument. If a NaN is required, one can be obtained in CUDA Python by other means, e.g. math.nan.
