Identifying Numeric Headers

The Standard C++ Library provides loads of functionality for numeric processing, a common programming task. Table 31.1 describes each of the standard headers that support numeric operations for standard C++.

Table 31.1. Standard Headers That Support Numeric Operations

Header	Purpose
<cmath>	Includes the standard C header <math.h> within the std namespace, providing standard math functions.
<cstdlib>	Includes the standard C header <stdlib.h> within the std namespace, providing random number generation.
<complex>	Provides a ...
