Defined in header <valarray>
template< class T >
valarray<T> tan( const valarray<T>& va );

For each element in va computes tangent of the value of the element.

Contents

Parameters

va - value array to apply the operation to

Return value

Value array containing tangents of the values in va.

Notes

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

The function can be implemented with the return type different from std::valarray. In this case, the replacement type has the following properties:

Possible implementation

template<class T>
valarray<T> tan(const valarray<T>& va)
{
    valarray<T> other = va;
    for (T &i : other) {
        i = tan(i);
    }
}
