(pow) . , std::pow .
:
Unqualified function (pow) is used to perform the computation. If such function is not available, std::pow is used due to argument dependent lookup.
Google.

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:
Google.
. .
  • const - std::valarray .
    :
    All const member functions of std::valarray are provided.
    Google.
    . .
  • std::valarray, std::slice_array, std::gslice_array, std::mask_array std::indirect_array .
    :
    std::valarray, std::slice_array, std::gslice_array, std::mask_array and std::indirect_array can be constructed from the replacement type.

    . .
  • , const std::valarray& .
    :
    All functions accepting a arguments of type const std::valarray& should also accept the replacement type.
    Google.
    . .
  • const std::valarray& const std::valarray& .
    :
    All functions accepting two arguments of type const std::valarray& should accept every combination of const std::valarray& and the replacement type.
