+\subsection{Overview}
+
+The main characteristics are:
+\begin{enumerate}
+\item exact algebra on arbitrarily big numbers, integers as well as fractions,
+\item floating point variants with user-chosen precision,
+\item implemented via macros compatible with expansion-only
+  context.
+\end{enumerate}
 
-\subsection{Missing things}
-
+`Arbitrarily big': this means with less than
+    |2^31-1|\digitstt{=\number"7FFFFFFF} digits, as most of the macros will
+    have to compute the length of the inputs and these lengths must be treatable
+    as \TeX{} integers, which are at most \digitstt{\number "7FFFFFFF} 
+    in absolute value.
+    This is a distant theoretical upper bound, 
+the true limitation is from the \emph{time} taken by the
+expansion-compatible algorithms, this will be commented upon soon.
+
+As just recalled, ten-digits numbers starting with a &3& already exceed the
+\TeX{} bound on integers; and \TeX{} does not have a native processing of
+floating point numbers (multiplication by a decimal number of a dimension
+register is allowed --- this is used for example by the
+\href{http://www.ctan.org/tex-archive/graphics/pgf/base}{pgf} basic math
+engine.)
+
+\TeX{} elementary operations on numbers are done via the non-expandable
+\emph{advance, multiply, \emph{and} divide} assignments. This was changed with
+\eTeX{}'s |\numexpr| which does expandable computations using standard infix
+notations with \TeX{} integers. But \eTeX{} did not modify the \TeX{} bound on
+acceptable integers, and did not add floating point support.
+
+The \href{http://www.ctan.org/pkg/bigintcalc}{bigintcalc} package by
+\textsc{Heiko Oberdiek} provided expandable operations (using some of |\numexpr|
+possibilities, when available) on arbitrarily big integers, beyond the \TeX{}
+bound. The present package does this again, using more of |\numexpr| (\xintname
+requires the \eTeX{} extensions) for higher speed, and also on fractions, not
+only integers. Arbitrary precision floating points operations are a derivative,
+and not the initial design goal.\footnote{currently (|v1.08|), the only
+  non-elementary operation implemented for floating point numbers is the
+  square-root extraction; furthermore no |NaN|'s nor error traps has been
+  implemented, only the notion of `scientific notation with a given number of
+  significant figures'.}${}^{\text{,\,}}$\footnote{multiplication of two floats
+  with |P=\string\xinttheDigits| digits is first done exactly then rounded to
+  |P| digits, rather than using a specially tailored multiplication for floating
+  point numbers which would be more efficient (it is a waste to evaluate fully
+  the multiplication result with |2P| or |2P-1| digits.)}
+
+The \LaTeX3 project has implemented
+expandably floating-point computations with 16 significant figures
+(\href{http://www.ctan.org/tex-archive/macros/latex/contrib/l3kernel}{l3fp}), 
+including special functions such as exp, log, sine and cosine.
 
-Although the latest release now implements arbitrary precision
-floating-point operations, and an expandable parser, it does not
-implement yet a mathematical library, in particular fractional powers,
-logarithm or trigonometric functions. 
+The \xintname package can be used for 24, 40, etc... significant figures but one
+rather quickly (not much beyond 100 figures perhaps) hits against a `wall'
+created by the constraint of expandability: currently, multiplying out two
+one-hundred digits numbers takes circa 80 or 90 times longer than for two
+ten-digits numbers, which is reasonable, but multiplying out two one-thousand
+digits numbers takes more than 500 times longer than for two one hundred-digits
+numbers. This shows that the algorithm is drifting from quadratic to cubic in
+that range. On my laptop multiplication of two 1000-digits numbers takes some
+seconds, so it can not be done routinely in a document.\footnote{without
+  entering 
+  into too much technical details, the 
+  source of this `wall' is that when dealing with two long operands, when one
+  wants to pick some digits from the second one, one has to jump above all
+  digits constituting the first one, which can not be stored away: expandability
+  forbids assignments to memory storage. One may envision some sophisticated
+  schemes, dealing with this problem in less naive ways, trying to move big
+  chunks of data higher up in the input stream and come back to it later,
+  etc...; but each `better' algorithm adds overhead for the smaller inputs. For
+  example, I have another version of addition which is twice faster on inputs
+  with 500 digits or more, but it is slightly less efficient for 50 digits or
+  less. This `wall' dissuaded me to look into implementing `intelligent'
+  multiplication which would be sub-quadratic in a model where storing and
+  retrieving from memory do not cost much.}
+
+The conclusion perhaps could be that it is in the end lucky that the speed gains
+brought by \xintname for expandable operations on big numbers do open some
+non-empty range of applicability in terms of the number of kept digits for
+routine floating point operations.
+
+The second conclusion, somewhat depressing after all the hard work, is
+that if one really wants to do computations with \emph{hundreds} of digits, one
+should drop the expandability requirement. And indeed, as clearly
+demonstrated long ago by the \href{http://www.ctan.org/pkg/pi}{pi
+  computing file} by \textsc{D. Roegel} one can program \TeX{} to
+compute with many digits at a much higher speed than what \xintname
+achieves: but, direct access to memory storage in one form or another
+seems a necessity for this kind of speed and one has to renounce at the
+complete expandability.\footnote{I could, naturally, be proven
+  wrong!}\,\footnote{The Lua\TeX{} project possibly makes endeavours
+  such as \xintname appear even more insane that they are, in truth.}
 
-% It is doubtful that I will engage into writing such a thing as the window
-% left open in terms of speed of computation from the constraint of
-% expandability is rather narrow. Up to a few dozen digits of floating point
-% precision perhaps, perhaps up to one hundred digits, but not much more (the
-% package is usable for one-shot, expensive, computations, though). And the
-% initial motivation was more into exact arithmetic operations with
-% (reasonably) arbitrarily long numbers. 
 
-% Besides, 
+\subsection{Missing things}
 
-The \LaTeX3 project has implemented expandably floating-point
-computations with 16 significant figures
-(\href{http://www.ctan.org/tex-archive/macros/latex/contrib/l3kernel}{\color{niceone}l3fp}),

-\hyperref[sec:comexpr]{\color{niceone}its documentation}.
+`Arbitrary-precision' floating-point
+operations are currently limited to the basic four operations, the power
+function with integer exponent, and the extraction of square-roots.
 
 \subsection{Some examples}
 
-The main initial goal is to allow computations with integers and fractions
-of arbitrary sizes.\footnote{Here and elsewhere, ``arbitrarily big'' means
-  roughly numbers with numerators and denominators having strictly less than
-  2\string^\string{31\string}=2147483648 digits. Memory constraints from the
-  \TeX{} engines presumably limit more the possible computations; but the
-  biggest constraint is the one of computation time, related to the
-  propriety of expandability. As explained in the text multiplying two one
-  thousand digits numbers is already expensive. On the other hand, floating
-  point computations are implemented with arbitrary precision, and one can
-  work comfortably with fifty digits of precision for example. }
+The main initial goal is to allow computations with integers and fractions of
+arbitrary sizes.
+
+Here are some examples. The first one uses only the base module \xintname, the
+next two require the \xintfracname package, which deals with fractions. Then two
+examples with the \xintgcdname package, one with the \xintseriesname package,
+and finally a computation with a float. Some inputs are simplified by the use
+of the \xintexprname package.

-\subsection{Expandability, (in)-efficiency}
-
-For some initially circumstantial reasons (related to the origins of the
-package) all macros performing computations are
-compatible with an expansion-only context. This programming constraint of
-expandability weighs in a lot on the computation time as the macros may have to
-shuffle around data containing hundreds of tokens: our current implementation
-of addition doesn't even achieve linear computation time! 
-
-For addition, I try to optimize things for the 50-500 digits range. I have a
-variant of addition which is twice faster on numbers with 1000 digits, but it is
-slower than the original for numbers with less than 200 digits, and adding to
-the code a fork to choose what to do would mean overhead; besides it wouldn't be
-that easy to use this variant of addition in the other routines such as
-multiplication and division. And multiplication is anyhow too slow on numbers
-with 1000 digits, even dividing the time by two would not be enough.
-
-Analogously to the not even linear addition, multiplication is worse than
-quadratic. Same causes, same effects. It is about cubic in the 100-1000
-digits range: on my laptop, with release |1.04| of the bundle, squaring a
-randomly chosen number with 200 digits takes about 4 hundredths of a 
-second, and squaring a 400 digits number about a quarter of a second. But
-squaring a 500 digits number is about 1.9 times as costly as one with 400
-digits, and squaring a 1000 digits number is 8 times more expensive than for a
-500 digits number (about 3.5 seconds). Implementation of a Gauss-Karatsuba
-scheme for intelligent multiplication has not been attempted so far. This kind
-of thing is motivating when one has instant memory access!
-
-As clearly demonstrated long ago by the
-\href{http://www.ctan.org/pkg/pi}{\color{niceone}pi computing file} by
-\textsc{D. Roegel} one can program \TeX{} to compute with many digits at a
-much higher speed than what \xintname achieves: but, direct access to memory
-storage in one form or another seems a necessity for this kind of speed
-and one has to renounce at the
-complete expandability.\footnote{I could, naturally,
-  be proven wrong!}\,\footnote{The Lua\TeX{} project possibly makes endeavours
-  such as \xintname appear even more insane that they are, in truth.}

 \def\x{\string{x\string}}
 
 This package was first included in release |1.03| of the \xintname bundle. The
 general rule of the bundle that each macro first expands (what comes first,
-fully) each one of its arguments applies. As in the previous documentation, |x|
-stands for something which will be internally embedded in a \csa{numexpr}, thus
-completely expanded and then must deliver a number obeying the TeX{} bounds. It
-may be a count register or something like |4*\count 255 + 17|, etc...
+fully) each one of its arguments applies. 
+
 
-|f| stands for a fraction (or a possibly `long' integer), or something which
-expands to a fraction or a possibly long integer. See the earlier section on
-fraction formats.
+|f| stands for an integer or a fraction (see \autoref{sec:inputs} for the
+accepted input formats) or something which expands to an integer or fraction. It
+is possible to use in the numerator or the denominator of |f| count
+registers\MyMarginNote{Not previously documented} and even expressions with
+infix arithmetic operators, under some rules which are explained in the previous
+\hyperlink{useofcount}{Use of count registers} section.
+
+As in the \hyperref[sec:comxint]{xint.sty} documentation, |x|
+stands for something which will internally be embedded in a \csa{numexpr}.
+It 
+may thus be a count register or something like |4*\count 255 + 17|, etc..., but
+must expand to an integer obeying the \TeX{} bound.
+
+The fraction format on output is the scientific notation for the `float' macros,
+and the |A/B[n]| format for all other fraction macros, with the exception of
+\csb{xintTrunc}, {\color{blue}\string\xint\-Round} (which produce decimal
+numbers) 
+and \csb{xintIrr}, \csb{xintJrr}, \csb{xintRawWithZeros} (which return an |A/B|
+with no trailing |[n]|, even if |B| turns out to be |1|). Use \csb{xintNum} for
+fractions a priori known to simplify to integers: |\xintNum {\xintAdd {2}{3}}|
+gives \digitstt{\xintNum {\xintAdd {2}{3}}} whereas |\xintAdd {2}{3}| returns
+\digitstt{\xintAdd {2}{3}}. Some macros (among them \csb{xintiTrunc},
+\csb{xintiRound}, and \csb{xintFac}) already produce integers on output.

+% Pour 1.08: dans \XINT_mul_enter et les modifs de 1.03
+% qui filtrent les courts, on pourrait croire  que le
+% second opérande a au moins quatre chiffres; mais le problème c'est que
+% ceci est appelé par \XINT_sqr. Et de plus \XINT_sqr est utilisé dans
+% la nouvelle routine d'extraction de racine carrée: je ne veux pas
+% rajouter l'overhead à \XINT_sqr de voir si a longueur est au moins 4.
+% Dilemme donc. Il ne semble pas y avoir d'autres accès
+% directs (celui de big fac n'est pas un problème). J'ai presque été
+% tenté de faire du 5x4, mais si on veut maintenir les résultats
+% intermédiaires sur 4n, il y a des complications. Par ailleurs,
+% je modifie aussi un petit peu la façon de coder la suite, compte tenu
+% du style que j'ai développé ultérieurement. Attention terminaison
+% modifiée pour le deuxième opérande.|

 % The commenting is currently (\docdate) very sparse. I was greatly helped in
 % the task of writing this expandable parser by the comments provided in
-% |l3fp-parse.dtx|. Clearly some ressemblance with the |l3fp| code will be
-% noticed, but there are some essential differences too. 
+% |l3fp-parse.dtx|. One will recognize in particular the idea of the `until'
+% macros; but I  have not looked into the actual |l3fp| code beyond the very
+% useful comments provided in its documentation. My main hurdle was that my data
+% has no a priori bound on its size; this led me to experiment with a technique
+% of storing and retrieving data expandably as \emph{names} of control
+% sequences. Also brace pairs have a special rôle related to the parsing of
+% |A/B[n]| fractions; this is \emph{experimental} and perhaps I will opt for
+% another solution at a later stage, 
+% for example one where such fractions should be user-prefixed by some marker,
+% for example |!| (which could not be confused there with its other use as
+% postfix symbol for the factorial function). There are thus some essential
+% differences of principle with the |l3fp| workplan. Of course, my task was
+% on the other hand simplified by the fact that I do not implement boolean
+% operators nor function names. To circumvent the potential hash-table impact I
+% have provided the macro creators |\xintNewExpr| and |\xintNewFloatExpr|.
+%
+% Version |1.08b| tries to correct a problem originating in the attempt to
+% attribute a special rôle to braces: expansion could be stopped by space
+% tokens,  as various macros tried to expand without grabbing what came next.
+% They now have a doubled |\romannumeral-`0|.
