va. (
tanh) . , std::tanh .:
Unqualified function (
tanh) is used to perform the computation. If such function is not available, std::tanh is used due to argument dependent lookup. std::valarray. , :
:
The function can be implemented with the return type different from std::valarray. In this case, the replacement type has the following properties:
- std::valarray,
std::slice_array,std::gslice_array,std::mask_arraystd::indirect_array.:std::valarray,std::slice_array,std::gslice_array,std::mask_arrayandstd::indirect_arraycan be constructed from the replacement type. - ,
const std::valarray&.:All functions accepting a arguments of typeconst std::valarray&should also accept the replacement type. const std::valarray&const std::valarray&.:All functions accepting two arguments of typeconst std::valarray&should accept every combination ofconst std::valarray&and the replacement type.
