Move the section on concrete numeric objects before the section on

concrete sequence objects, since their API is simpler.

+\subsection{Complex Number Objects \label{complexObjects}}
+
+\obindex{complex number}
+Python's complex number objects are implemented as two distinct types
+when viewed from the C API:  one is the Python object exposed to
+Python programs, and the other is a C structure which represents the
+actual complex number value.  The API provides functions for working
+with both.
+
+\subsubsection{Complex Numbers as C Structures}
+
+Note that the functions which accept these structures as parameters
+and return them as results do so \emph{by value} rather than
+dereferencing them through pointers.  This is consistent throughout
+the API.
+
+\begin{ctypedesc}{Py_complex}
+The C structure which corresponds to the value portion of a Python
+complex number object.  Most of the functions for dealing with complex
+number objects use structures of this type as input or output values,
+as appropriate.  It is defined as:
+
+\begin{verbatim}
+typedef struct {
+   double real;
+   double imag;
+} Py_complex;
+\end{verbatim}
+\end{ctypedesc}
+
+\begin{cfuncdesc}{Py_complex}{_Py_c_sum}{Py_complex left, Py_complex right}
+Return the sum of two complex numbers, using the C
+\ctype{Py_complex} representation.
+\end{cfuncdesc}
+
+\begin{cfuncdesc}{Py_complex}{_Py_c_diff}{Py_complex left, Py_complex right}
+Return the difference between two complex numbers, using the C
+\ctype{Py_complex} representation.
+\end{cfuncdesc}
+
+\begin{cfuncdesc}{Py_complex}{_Py_c_neg}{Py_complex complex}
+Return the negation of the complex number \var{complex}, using the C
+\ctype{Py_complex} representation.
+\end{cfuncdesc}
+
+\begin{cfuncdesc}{Py_complex}{_Py_c_prod}{Py_complex left, Py_complex right}
+Return the product of two complex numbers, using the C
+\ctype{Py_complex} representation.
+\end{cfuncdesc}
+
+\begin{cfuncdesc}{Py_complex}{_Py_c_quot}{Py_complex dividend,
+                                          Py_complex divisor}
+Return the quotient of two complex numbers, using the C
+\ctype{Py_complex} representation.
+\end{cfuncdesc}
+
+\begin{cfuncdesc}{Py_complex}{_Py_c_pow}{Py_complex num, Py_complex exp}
+Return the exponentiation of \var{num} by \var{exp}, using the C
+\ctype{Py_complex} representation.
+\end{cfuncdesc}
+
+
+\subsubsection{Complex Numbers as Python Objects}
+
+\begin{ctypedesc}{PyComplexObject}
+This subtype of \ctype{PyObject} represents a Python complex number object.
+\end{ctypedesc}
+
+\begin{cvardesc}{PyTypeObject}{PyComplex_Type}
+This instance of \ctype{PyTypeObject} represents the Python complex 
+number type.
+\end{cvardesc}
+
+\begin{cfuncdesc}{int}{PyComplex_Check}{PyObject *p}
+Returns true if its argument is a \ctype{PyComplexObject}.
+\end{cfuncdesc}
+
+\begin{cfuncdesc}{PyObject*}{PyComplex_FromCComplex}{Py_complex v}
+Create a new Python complex number object from a C
+\ctype{Py_complex} value.
+\end{cfuncdesc}
+
+\begin{cfuncdesc}{PyObject*}{PyComplex_FromDoubles}{double real, double imag}
+Returns a new \ctype{PyComplexObject} object from \var{real} and \var{imag}.
+\end{cfuncdesc}
+
+\begin{cfuncdesc}{double}{PyComplex_RealAsDouble}{PyObject *op}
+Returns the real part of \var{op} as a C \ctype{double}.
+\end{cfuncdesc}
+
+\begin{cfuncdesc}{double}{PyComplex_ImagAsDouble}{PyObject *op}
+Returns the imaginary part of \var{op} as a C \ctype{double}.
+\end{cfuncdesc}
+
+\begin{cfuncdesc}{Py_complex}{PyComplex_AsCComplex}{PyObject *op}
