valarray<T> operator+() const; | (1) | |

valarray<bool> operator!() const; | (4) |
Applies unary operators to each element in the numeric array.
(none).
A numeric array containing elements with values obtained by applying corresponding operator to the values in *this
.
(none).
Each of the operators can only be instantiated if the following requirements are met:
T
T
(1-3) or bool
(4). The function can be implemented with the return type different from std::valarray
. In this case, the replacement type has the following properties:
const
member functions of std::valarray
are provided. 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&
except begin()
and end()
(since C++11) should also accept the replacement type. const std::valarray&
should accept every combination of const std::valarray&
and the replacement type.
