Other Libraries

C++ provides some other class libraries that are more specialized than the examples covered in this chapter. The complex header file provides a complex class template for complex numbers, with specializations for float, long, and long double. The class provides standard complex number operations along with standard functions that can be used with complex numbers.

The valarray header file provides a valarray template class. This class template is designed to represent numeric arrays and provides support for a variety of numeric array operations, such as adding the contents of one array to another, applying math functions to each element of an array, and applying linear algebra operations to arrays.
