+\subsection{Package overview}\label{ssec:cfracoverview}
-\subsection{Package overview}
+The package computes partial quotients and convergents of a fraction, or
+conversely start from coefficients and obtain the corresponding fraction; three
+macros \csbxint {CFrac}, \csbxint {GCFrac} and \csbxint {GGCFrac} are
+for typesetting (the first two assume that the coefficients are numeric
+quantities acceptable by the \xintfracname \csbxint{Frac} macro, the
+last one will display arbitrary material), the others
+can be nested (if applicable) or see their outputs further processed by other
+macros from the \xintname bundle, particularly the macros of \xinttoolsname
+dealing with sequences of braced items or comma separated lists.
A \emph{simple} continued fraction has coefficients
-|[c0,c1,...,cN]| (usually called partial quotients, but I really
+|[c0,c1,...,cN]| (usually called partial quotients, but I
dislike this entrenched terminology), where |c0| is a positive or
-negative integer and the others are positive integers. As we will
-see it is possible with \xintcfracname to specify the coefficient
-function |c:n->cn|. Note that the index then starts at zero as
-indicated. With the |amsmath| macro |\cfrac| one can display such a
-continued fraction as
+negative integer and the others are positive integers.
+
+
+Typesetting is usually done via the |amsmath| macro |\cfrac|:
+\centeredline{|\[ c_0 + \cfrac{1}{c_1+\cfrac1{c_2+\cfrac1{c_3+\cfrac1{\ddots}}}}\]|}
\[ c_0 + \cfrac{1}{c_1+\cfrac1{c_2+\cfrac1{c_3+\cfrac1{\ddots}}}}\]
Here is a concrete example:
-\[ \xintFrac {208341/66317}=\xintCFrac {208341/66317}\] But the
-difference with |amsmath|'s |\cfrac| is that this was input as
-\centeredline{|\[ \xintFrac {208341/66317}=\xintCFrac
- {208341/66317} \]|} The command \csbxint{CFrac} produces in two
-expansion steps the whole thing with the many chained |\cfrac|'s and all
-necessary braces, ready to be printed, in math mode. This is \LaTeX{}
-only and with the |amsmath| package (we shall mention another method for
-Plain \TeX{} users of |amstex|).
-
-A \emph{generalized} continued fraction has the same structure but
-the numerators are not restricted to be ones, and numbers used in
-the continued fraction may be arbitrary, also fractions,
-irrationals, indeterminates. The \emph{centered} continued
-fraction associated to a rational number is an

+%
+\[ \xintFrac {208341/66317}=\xintCFrac {208341/66317}\]%
+%
+But it is the command \csbxint{CFrac} which did all the work of \emph{computing}
+the continued fraction \emph{and} using |\cfrac| from |amsmath| to typeset
+it.
+
+A \emph{generalized} continued fraction has the same structure but the
+numerators are not restricted to be $1$, and numbers used in the continued
+fraction may be arbitrary, also fractions, irrationals, complex,
+indeterminates.\footnote{\xintcfracname may be used with indeterminates,
+ for basic conversions from one inline format to another, but not for
+ actual computations. See \csbxint{GGCFrac}.}
+The \emph{centered} continued fraction is an
example:
-\[ \xintFrac {915286/188421}=\xintGCFrac {\xintFtoCC {915286/188421}}
+\centeredline{|\[ \xintFrac {915286/188421}=\xintGCFrac
+ {5+-1/7+1/39+-1/53+-1/13} \]|}
+\[ \xintFrac {915286/188421}=\xintGCFrac {5+-1/7+1/39+-1/53+-1/13}
=\xintCFrac {915286/188421}\]
- \centeredline{|\[ \xintFrac {915286/188421}=\xintGCFrac {\xintFtoCC
- {915286/188421}} \]|}
+
The command \csbxint{GCFrac}, contrarily to
-\csbxint{CFrac}, does not compute anything, it just typesets. Here, it is the
-command \csbxint{FtoCC} which did the computation of
-the centered continued fraction of |f|. Its output has the `inline format'
-described in the next paragraph. In the display, we also used \csa{xintCFrac}
-(code not shown), for comparison of the two types of continued fractions.

+The package macros are expandable and may be nested (naturally \csa{xintCFrac}
+and \csa{xintGCFrac} must be at the top level, as they deal with typesetting).
+Thus
+ \centeredline{|\[\xintGCFrac {\xintFtoCC{915286/188421}}\]|}
+produces
+\[\xintGCFrac {\xintFtoCC{915286/188421}}\]

+and convergents. The macro \csbxint{FGtoC} outputs as a sequence of braced items

+lower and upper bound:
-\smallskip The actual computation of the list of all 36 convergents accounts for

-formula gives the continued fraction of $e-1$). One can with no problem compute
-much bigger convergents. Let's get the 200th convergent. It turns out to
-have the same first 268 digits after the decimal point as $e-1$. Higher
-convergents get more and more digits in proportion to their index: the 500th
-convergent already gets 799 digits correct! To allow speedy compilation of the

+% The actual computation of the list of all 36 convergents accounts for
+% only 8\% of the total time (total time equal to about 5 hundredths of a second
+% in my testing, on my laptop): another 80\% is occupied with the computation of
+% the truncated decimal expansions (and the addition of 1 to everything as the
+% formula gives the continued fraction of $e-1$).
+
+One can with no problem compute
+much bigger convergents. Let's get the 200th convergent. It turns out to
+have the same first 268 digits after the decimal point as $e-1$. Higher
+convergents get more and more digits in proportion to their index: the 500th
+convergent already gets 799 digits correct! To allow speedy compilation of the
+source of this document when the need arises, I limit here to the 200th
+convergent.
+% (getting the 500th took about 1.2s on my laptop last time I tried,
+% and the 200th convergent is obtained ten times faster).

+% The commenting is currently (\docdate) very sparse. Release |1.09m|
+% (|2014/02/26|) has modified a few things: |\xintFtoCs| and
+% |\xintCntoCs| insert spaces after the commas, |\xintCstoF| and
+% |\xintCstoCv| authorize spaces in the input also before the commas,
+% |\xintCntoCs| does not brace the produced coefficients, new macros
+% |\xintFtoC|, |\xintCtoF|, |\xintCtoCv|, |\xintFGtoC|, and
+% |\xintGGCFrac|. All uses of |\W| and many instances of |\Z| as
+% delimiters removed, this was in some cases not very safe (for example
+% in the treatment of the optional arguments to some macros). Actually I
+% have also replaced everywhere else in the bundle the use of |\Z| in
+% the treatment of macros with optional arguments with the safer
+% |\xint_relax| (the more recent |\xintSeq| already used |\xint_bye|).
