26.6.3 valarray non-member operations [valarray.nonmembers]

26.6.3.1 valarray binary operators [valarray.binary]

template<class T> valarray<T> operator* (const valarray<T>&, const valarray<T>&); template<class T> valarray<T> operator/ (const valarray<T>&, const valarray<T>&); template<class T> valarray<T> operator% (const valarray<T>&, const valarray<T>&); template<class T> valarray<T> operator+ (const valarray<T>&, const valarray<T>&); template<class T> valarray<T> operator- (const valarray<T>&, const valarray<T>&); template<class T> valarray<T> operator^ (const valarray<T>&, const valarray<T>&); template<class T> valarray<T> operator& (const valarray<T>&, const valarray<T>&); template<class T> valarray<T> operator| (const valarray<T>&, const valarray<T>&); template<class T> valarray<T> operator<< (const valarray<T>&, const valarray<T>&); template<class T> valarray<T> operator>> (const valarray<T>&, const valarray<T>&);

1

Each of these operators may only be instantiated for a type T to which the indicated operator can be applied and for which the indicated operator returns a value which is of type T or which can be unambiguously implicitly converted to type T.

2

Each of these operators returns an array whose length is equal to the lengths of the argument arrays. Each element of the returned array is initialized with the result of applying the indicated operator to the corresponding elements of the argument arrays.

3

If the argument arrays do not have the same length, the behavior is undefined.

template<class T> valarray<T> operator* (const valarray<T>&, const T&); template<class T> valarray<T> operator* (const T&, const valarray<T>&); template<class T> valarray<T> operator/ (const valarray<T>&, const T&); template<class T> valarray<T> operator/ (const T&, const valarray<T>&); template<class T> valarray<T> operator% (const valarray<T>&, const T&); template<class T> valarray<T> operator% (const T&, const valarray<T>&); template<class T> valarray<T> operator+ (const valarray<T>&, const T&); template<class T> valarray<T> operator+ (const T&, const valarray<T>&); template<class T> valarray<T> operator- (const valarray<T>&, const T&); template<class T> valarray<T> operator- (const T&, const valarray<T>&); template<class T> valarray<T> operator^ (const valarray<T>&, const T&); template<class T> valarray<T> operator^ (const T&, const valarray<T>&); template<class T> valarray<T> operator& (const valarray<T>&, const T&); template<class T> valarray<T> operator& (const T&, const valarray<T>&); template<class T> valarray<T> operator| (const valarray<T>&, const T&); template<class T> valarray<T> operator| (const T&, const valarray<T>&); template<class T> valarray<T> operator<<(const valarray<T>&, const T&); template<class T> valarray<T> operator<<(const T&, const valarray<T>&); template<class T> valarray<T> operator>>(const valarray<T>&, const T&); template<class T> valarray<T> operator>>(const T&, const valarray<T>&);

4

Each of these operators may only be instantiated for a type T to which the indicated operator can be applied and for which the indicated operator returns a value which is of type T or which can be unambiguously implicitly converted to type T.

5

Each of these operators returns an array whose length is equal to the length of the array argument. Each element of the returned array is initialized with the result of applying the indicated operator to the corresponding element of the array argument and the non-array argument.

26.6.3.2 valarray logical operators [valarray.comparison]

template<class T> valarray<bool> operator== (const valarray<T>&, const valarray<T>&); template<class T> valarray<bool> operator!= (const valarray<T>&, const valarray<T>&); template<class T> valarray<bool> operator< (const valarray<T>&, const valarray<T>&); template<class T> valarray<bool> operator> (const valarray<T>&, const valarray<T>&); template<class T> valarray<bool> operator<= (const valarray<T>&, const valarray<T>&); template<class T> valarray<bool> operator>= (const valarray<T>&, const valarray<T>&); template<class T> valarray<bool> operator&& (const valarray<T>&, const valarray<T>&); template<class T> valarray<bool> operator|| (const valarray<T>&, const valarray<T>&);

1

Each of these operators may only be instantiated for a type T to which the indicated operator can be applied and for which the indicated operator returns a value which is of type bool or which can be unambiguously implicitly converted to type bool.

2

Each of these operators returns a bool array whose length is equal to the length of the array arguments. Each element of the returned array is initialized with the result of applying the indicated operator to the corresponding elements of the argument arrays.

3

If the two array arguments do not have the same length, the behavior is undefined.

template<class T> valarray<bool> operator==(const valarray<T>&, const T&); template<class T> valarray<bool> operator==(const T&, const valarray<T>&); template<class T> valarray<bool> operator!=(const valarray<T>&, const T&); template<class T> valarray<bool> operator!=(const T&, const valarray<T>&); template<class T> valarray<bool> operator< (const valarray<T>&, const T&); template<class T> valarray<bool> operator< (const T&, const valarray<T>&); template<class T> valarray<bool> operator> (const valarray<T>&, const T&); template<class T> valarray<bool> operator> (const T&, const valarray<T>&); template<class T> valarray<bool> operator<=(const valarray<T>&, const T&); template<class T> valarray<bool> operator<=(const T&, const valarray<T>&); template<class T> valarray<bool> operator>=(const valarray<T>&, const T&); template<class T> valarray<bool> operator>=(const T&, const valarray<T>&); template<class T> valarray<bool> operator&&(const valarray<T>&, const T&); template<class T> valarray<bool> operator&&(const T&, const valarray<T>&); template<class T> valarray<bool> operator||(const valarray<T>&, const T&); template<class T> valarray<bool> operator||(const T&, const valarray<T>&);

4

Each of these operators may only be instantiated for a type T to which the indicated operator can be applied and for which the indicated operator returns a value which is of type bool or which can be unambiguously implicitly converted to type bool.

5

Each of these operators returns a bool array whose length is equal to the length of the array argument. Each element of the returned array is initialized with the result of applying the indicated operator to the corresponding element of the array and the non-array argument.

26.6.3.3 valarray transcendentals [valarray.transcend]

template<class T> valarray<T> abs (const valarray<T>&); template<class T> valarray<T> acos (const valarray<T>&); template<class T> valarray<T> asin (const valarray<T>&); template<class T> valarray<T> atan (const valarray<T>&); template<class T> valarray<T> atan2 (const valarray<T>&, const valarray<T>&); template<class T> valarray<T> atan2(const valarray<T>&, const T&); template<class T> valarray<T> atan2(const T&, const valarray<T>&); template<class T> valarray<T> cos (const valarray<T>&); template<class T> valarray<T> cosh (const valarray<T>&); template<class T> valarray<T> exp (const valarray<T>&); template<class T> valarray<T> log (const valarray<T>&); template<class T> valarray<T> log10(const valarray<T>&); template<class T> valarray<T> pow (const valarray<T>&, const valarray<T>&); template<class T> valarray<T> pow (const valarray<T>&, const T&); template<class T> valarray<T> pow (const T&, const valarray<T>&); template<class T> valarray<T> sin (const valarray<T>&); template<class T> valarray<T> sinh (const valarray<T>&); template<class T> valarray<T> sqrt (const valarray<T>&); template<class T> valarray<T> tan (const valarray<T>&); template<class T> valarray<T> tanh (const valarray<T>&);

1

Each of these functions may only be instantiated for a type T to which a unique function with the indicated name can be applied (unqualified). This function shall return a value which is of type T or which can be unambiguously implicitly converted to type T.
