Global_Declarations

 The following declarations are used by the complex package but they
 are not members of a particular class:

 typedef int (*cxxl_p_complex_error_t)(c_exception &error_information);
 static const complex_zero (0, 0);
 cxxl_p_complex_error_t set_complex_error(cxxl_p_complex_error_t p_complex_error

complex
 This class contains methods to perform complex value operations.
 These include arithmetic, assignment, and comparison operators for
 complex values; Cartesian and polar coordinates; mixed-mode
 arithmetic; and mathematical functions for complex values equivalent
 to standard mathematical functions.

c_exception
 Objects of this class handle exceptions for complex arithmetic. This
 includes information on functions, parameters, error types, and
 default return values.
