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. This is done by applying tan (unqualified) function.

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:

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

Possible implementation

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