# <valarray>

**Visual Studio 2015**

Defines the template class valarray and numerous supporting template classes and functions.

#include <valarray>

These template classes and functions are permitted unusual latitude in the interest of improved performance. Specifically, any function returning type **valarray<**T1**>** may return an object of some other type T2. In that case, any function that accepts one or more arguments of type **valarray<**T2**>** must have overloads that accept arbitrary combinations of those arguments, each replaced with an argument of type T2.
