-plus and minus signs, followed by some string of zeros, followed by digits.
-
-The letter \texttt{x} stands for something which will be inserted in-between a
-|\numexpr| and a |\relax|. It will thus be completely expanded and must give an
-integer obeying the \TeX{} bounds. Thus, it may be for example a count register,
-or itself a \csa{numexpr} expression, or just a number written explicitely with
-digits or something like |4*\count 255 + 17|, etc...
-
-For the rules regarding direct use of count registers or \csa{numexpr}
-expression, in the argument to the package macros, see the
-\hyperlink{useofcount}{use of count section} in \autoref{sec:inputs}.
-
-Some of these macros are extended by \xintfracname to accept fractions on input,
-and, generally, to output a fraction. But this means that additions,
-subtractions, multiplications output fractions and not integers; to guarantee
-the integer format on output when the inputs are integers, the original
-integer-only macros \csa{xintAdd}, \csa{xintSub}, \csa{xintMul} remain available
-under the names \csa{xintiAdd}, \csa{xintiSub}, \csa{xintiMul}. Even the
-original integer-only macros may now accept fractions on input as long as they
-are integers in disguise; they still produce on output integers without any
-forward slash mark nor trailing |[n]|. On the other hand macros such as
-|\xintAdd| will output fractions |A/B[n]|, with |B| present even if its value is
-one. To remove this unit denominator and convert the |[n]| part into explicit
-zeros, one has \csbxint{Num} (if one is certain to deal with an integer; see
-also \csbxint{PRaw}). This is mandatory when the computation result is fetched
-into a context where \TeX{} expects a number (assuming it does not exceed
-@2^31@). See the also the \xintfracname \hyperref[sec:comfrac]{documentation}
-for more information on how macros of \xintname are modified after loading
-\xintfracname (or \xintexprname).
-
-
-Package \xintname also provides some general macro programming or token
-manipulation utilities (expandable as well as non-expandable), which are
-described in the next section (\autoref{sec:utilsxint}).

-\subsection{\csbh{xintRev}} \label{xintRev}
-
-\csa{xintRev\n} will revert the order of the digits of the number,
-keeping the optional sign. Leading zeros
-resulting from the operation are not removed (see the
-\csa{xintNum} macro for this). This macro and all other
-macros dealing with numbers first expand `fully' their arguments.

- {=\xintLen{-12345678901234567890123456789}}} Extended by \xintfracname to
-fractions: the length of |A/B[n]| is the length of |A| plus the length of |B|
-plus the absolute value of |n| and minus one (an integer input as |N| is
-internally represented in a form equivalent to |N/1[0]| so the minus one means
-that the extended \csa{xintLen}
-behaves the same as the original for integers).
-\centeredline{|\xintLen{-1e3/5.425}|\digitstt
- {=\xintLen{-1e3/5.425}}}
-The length is computed on the |A/B[n]| which would have been returned by
-\csbxint{Raw}: |\xintRaw {-1e3/5.425}|\digitstt{=\xintRaw {-1e3/5.425}}.
-
-Let's point out that the whole thing should sum up to
-less than circa @2^{31}@, but this is a bit theoretical.
-
-|\xintLen| is only for numbers or fractions. See \csbxint{Length} for counting
-tokens (or rather braced groups), more generally.

-\subsection{\csbh{xintDigitsOf}}\label{xintDigitsOf}

-\subsection{\csbh{xintPow}}\label{xintiPow}

-\csa{xintPow\n\x} returns |N^x|. When |x| is zero, this is 1. If |N| is zero and
-|x<0|, if \verb+|N|>1+ and |x<0| negative, or if \verb+|N|>1+ and |x>999999999|,
-then an error is raised. |2^999999999| has \np{301029996} digits; each exact
-multiplication of two one thousand digits numbers already takes a few seconds,
-so needless to say this bound is completely irrealistic. Already |2^9999| has
-\np{3010} digits,\footnote{on my laptop |\string\xintiPow \{2\}\{9999\}|
- obtains all |3010| digits in about ten or eleven seconds. In contrast, the
- float versions for
- |8|, |16|, |24|, or even more significant figures, do their jobs in circa one
- hundredth of a second (|1.08b|). This is done without |log|/|exp| which are
- not (yet?) implemented in \xintfracname. The \LaTeX3
- \href{http://www.ctan.org/tex-archive/macros/latex/contrib/l3kernel}{l3fp}
- does this with |log|/|exp| and is ten times faster (|16| figures only).} so I
-should perhaps lower the bound to |99999|.
-
-Extended by \xintfracname to fractions (\csbxint{Pow}) and also to floats
-(\csbxint{FloatPow}). Negative
-exponents do not then cause errors anymore. The float version is able to deal
-with things such as
-|2^999999999| without any problem. For example

-chooses to execute either the \meta{A}, \meta{B} or \meta{C} code,
-depending on its first argument. This first argument should be anything
-expanding to either |-1|, |0| or |1| (a count register should be
-prefixed by |\the| and a |\numexpr...\relax| also should be prefixed by
-|\the|). This utility is provided to help construct expandable macros

-\subsection{\csbh{xintFac}}\label{xintiFac}
-
-\csa{xintFac\x} returns the factorial. It is an error if the
-argument is negative or at least @10^6@. It is not recommended to
-launch the computation of things such as @100000!@, if you need
-your computer for other tasks. Note that the argument is of the |x| type, it
-must obey the \TeX{} bounds, but on the other hand may involve count registers
-and even arithmetic operations as it will be completely expanded inside a
-|\numexpr|.
-
-With \xintfracname loaded, the macro also
-accepts a fraction as argument, as long as this fraction turns out to be an
-integer: |\xintFac {66/3}|\digitstt{=\xintFac {66/3}}.
-
-% the construct |\xintFac{\xintAdd {2}{3}}| will fail,

-is euclidean division: |N = QM + R|, |0|${}\leq{}$\verb+R < |M|+. So the
-remainder is always non-negative and the formula |N = QM + R|
-always holds independently of the signs of |N| or |M|. Division by
-zero is an error (even if |N| vanishes) and returns |{0}{0}|.

-\csa{xintDSR\n} is decimal shift right, \emph{i.e.} it removes the last digit
-(keeping the sign), equivalently it is the closest integer to |N/10| when
-starting at zero.
-
-\subsection{\csbh{xintDSH}}\label{xintDSH}
-
-\csa{xintDSH\x\n} is parametrized decimal shift. When |x| is
-negative, it is like iterating \csa{xintDSL} \verb+|x|+ times
-(\emph{i.e.} multiplication by @10^{-@|x|@}@). When |x| positive,
-it is like iterating \csa{DSR} |x| times (and is more efficient), and for a
-non-negative |N| this is thus the same as the
-quotient from the euclidean division by |10^x|.
-
-\subsection{\csbh{xintDSHr}, \csbh{xintDSx}}\label{xintDSHr}\label{xintDSx}
-{\small New in release |1.01|.\par}
-
-\csa{xintDSHr\x\n} expects |x| to be zero or positive and it returns
-then a value |R| which is correlated to the value |Q| returned by
-\csa{xintDSH\x\n} in the following manner:
-\begin{itemize}
-\item if |N| is
- positive or zero, |Q| and |R| are the quotient and remainder in
- the euclidean division by |10^x| (obtained in a more efficient
- manner than using \csa{xintDivision}),
-\item if |N| is negative let
- |Q1| and |R1| be the quotient and remainder in the euclidean
- division by |10^x| of the absolute value of |N|. If |Q1|
- does not vanish, then |Q=-Q1| and |R=R1|. If |Q1| vanishes, then
- |Q=0| and |R=-R1|.
-\item for |x=0|, |Q=N| and |R=0|.
-\end{itemize}
-So one has |N = 10^x Q + R| if |Q| turns out to be zero or
-positive, and |N = 10^x Q - R| if |Q| turns out to be negative,
-which is exactly the case when |N| is at most |-10^x|.
-
-
-\csa{xintDSx\x\n} for |x| negative is exactly as
-\csa{xintDSH\x\n}, \emph{i.e.} multiplication by @10^{-@|x|@}@.
-For |x| zero or positive it returns the two numbers |{Q}{R}|
-described above, each one within braces. So |Q| is
-\csa{xintDSH\x\n}, and |R| is \csa{xintDSHr\x\n}, but computed
-simultaneously.

-{\small This has been modified in release |1.01|.\par}
-
-\csa{xintDecSplit\x\n} cuts the number into two pieces (each one within a
-pair of enclosing braces). First the sign if present is \emph{removed}.
-Then, for |x| positive or null, the second piece contains the |x| least
-significant digits (\emph{empty} if |x=0|) and the first piece the remaining
-digits (\emph{empty} when |x| equals or exceeds the length of |N|).
-Leading zeros in the second piece are not removed. When |x| is negative
-the first piece contains the \verb+|x|+ most significant digits and the
-second piece the remaining digits (\emph{empty} if @|x|@ equals or exceeds
-the length of |N|). Leading zeros in this second piece are not removed.
-So the absolute value of the original number is always the concatenation
-of the first and second piece.

+\label{xintbreakloopanddo}
+\label{xintloopskiptonext}
+{\small New with release |1.09g|.\par}
+
+|\xintloop|\meta{stuff}|\iftest ... \repeat| is an expandable loop compatible
+with nesting. If a sub-loop is to be used all the material from the start and up
+to the complete subloop inclusive should be braced; these braces will be removed
+and do not create a group.
+
+As this loop and \csbxint{iloop} will primarily be of interest to experienced
+\TeX{} macro programmers, my description will assume that the user is
+knowledgeable enough. The loop and its various constituents are declared short,
+they can not handle |\par| tokens or empty lines.
+
+One can abort the loop with \csbxint{breakloop}; this should not be used in the
+final test, and one should expand the |\fi| from the corresponding test before.
+One has also \csbxint{breakloopanddo} whose first argument will be inserted in
+the token stream after the loop; one may need a macro such as |\xint_afterfi| to
+move the whole thing after the |\fi|, as a simple |\expandafter| will not be
+enough.
+
+One will usually employ some count registers to manage the exit test from the
+loop; this breaks expandability, see \csbxint{iloop} for an expandable integer
+indexed loop. Use in alignments will be complicated by the fact that cells
+create groups, and also from the fact that any encountered unexpandable material
+will cause the \TeX{} input scanner to insert |\endtemplate| on each encountered
+|&| or |\cr|; thus |\xintbreakloop| may not work as expected, but the situation
+can be resolved via |\xint_firstofone{&}| or use of |\TAB| with |\def\TAB{&}|.
+It is thus simpler for alignments to use rather than \csbxint{loop} either the
+expandable \csbxint{ApplyUnbraced} or the non-expandable but alignment
+compatible \csbxint{ApplyInline}, \csbxint{For} or \csbxint{For*}.
+
+As an example, let us suppose we have two macros |\A|\marg{i}\marg{j} and
+|\B|\marg{i}\marg{j} behaving like (small) integer valued matrix entries, and we
+want to define a macro |\C|\marg{i}\marg{j} giving the matrix product (|i| and
+|j| may be count registers). We will assume that |\A[I]| expands to the number
+of rows, |\A[J]| to the number of columns and want the produced |\C| to act in
+the same manner. The code is very dispendious in use of |\count| registers, not
+optimized in any way, not made very robust (the defined macro can not have the
+same name as the first two matrices for example), we just wanted to quickly
+illustrate use of the nesting capabilities of |\xintloop|.\footnote{for a more sophisticated implementation of matrix multiplication, inclusive of determinants, inverses, and display utilities, with entries big integers or decimal numbers or even fractions see \url{http://tex.stackexchange.com/a/143035/4686} from November 11, 2013.}

+{\small New with release |1.09g|.\par}
+
+\csa{xintiloop}|[start+delta]|\meta{stuff}|\iftest ... \repeat| is a completely
+expandable nestable loop having access via \csbxint{iloopindex} to the integer
+index of the iteration, with starting value |start| (which may be a |\count|)
+and increment |delta| (\emph{id.}). Currently |[start+delta]| is a
+\emph{mandatory argument}, it is an error to omit it; perhaps a future release
+will make it optional with default |1+1|. A space after the closing square
+bracket is not significant, it will be ignored. Spaces inside the square
+brackets will also be ignored as the two arguments are first given to a
+|\numexpr...\relax|.
+
+As with \csbxint{loop}, this tool will mostly be of interest to advanced users.
+As is the case for its variant, it is declared short and can not handle directly
+|\par| tokens or empty lines. For nesting, one puts inside braces all the
+material from the start (immediately after |[start+delta]|) and up to and
+inclusive of the inner loop, these braces will be removed and do not create a
+loop. In case of nesting, \csbxint{outeriloopindex} gives access to the index of
+the outer loop. If needed one could write on its model a macro giving access to
+the index of the outer outer loop (or even to the |nth| outer loop).
+
+
+The \csa{xintiloopindex} and \csa{xintouteriloopindex} can not be used inside
+braces, and generally speaking this means they should be expanded first when
+given as argument to a macro, and that this macro receives them as delimited
+arguments, not braced ones. Or, but naturally this will break expandability, one
+can assign the value of \csa{xintiloopindex} to some |\count|. Both
+\csa{xintiloopindex} and \csa{xintouteriloopindex} extend to the litteral
+representation of the index, thus in |\ifnum| tests, if it comes last one has to
+correctly end the macro with a |\space|, or encapsulate it in a
+|\numexpr..\relax|.
+
+When the repeat-test of the loop is, for example, |\ifnum\xintiloopindex<10
+\repeat|, this means that the last iteration will be with |\xintiloopindex=10|
+(assuming |delta=1|). There is also |\ifnum\xintiloopindex=10 \else\repeat| to
+get the last iteration to be the one with |\xintiloopindex=10|.
+
+One has \csbxint{breakiloop} and \csbxint{breakiloopanddo} to abort the
+loop, \csbxint{iloopskiptonext} to abort the current iteration and skip to the
+next, \hyperref[xintiloopskipandredo]{\ttfamily\hyphenchar\font45 \char92
+ xintiloopskip\-and\-redo} to skip to the end of the current iteration and redo
+it with the same value of the index (something else will have to change for this
+not to become an eternal loop\dots ).
+
+Inside alignments, if the looped-over text contains a |&| or a |\cr|, any
+un-expandable material before a \csbxint{iloopindex} will make it fail because
+of |\endtemplate|; in such cases one can always either replace |&| by a macro
+expanding to it or replace it by a suitable |\firstofone{&}|, and similarly for
+|\cr|.
+
+As an example, let us construct an |\edef\z{...}| which will define |\z| to be a
+list of prime numbers:

+\subsection{A table of factorizations}
+
+As one more example with \csbxint{iloop} let us use an alignment to display the
+factorization of some numbers. The loop will actually only play a minor r\^ole
+here, just handling the row index, the row contents being almost entirely
+produced via a macro |\factorize|. The factorizing macro does not use
+|\xintiloop| as it didn't appear to be the convenient tool. As |\factorize| will
+have to be used on |\xintiloopindex|, it has been defined as a delimited macro.
+
+To spare some fractions of a second in the compilation time of this document
+(which has many many other things to do), \number"7FFFFFED{} and
+\number"7FFFFFFF, which turn out to be prime numbers, are not given to
+|factorize| but just typeset directly; this illustrates use of
+\csbxint{iloopskiptonext}.

+The \hyperref[floatfactorize]{table} has been made into a float which appears
+\vpageref{floatfactorize}. Here is now the code for factorization; the
+conditionals use

+\texttt{\char92\string@secondoftwo}, or, simpler still in \LaTeX{} context, the
+|\ifnumequal|, |\ifnumless| \dots, utilities from the package |etoolbox| which
+do exactly that under the hood. Only \TeX{} acceptable numbers are treated here,
+but it would be easy to make a translation and use the \xintname macros, thus
+extending the scope to big numbers; naturally up to a cost in speed.
+
+The reason for some strange looking expressions is to avoid arithmetic overflow.

+digits or something like |4*\count 255 + 17|, etc...
+
+For the rules regarding direct use of count registers or \csa{numexpr}
+expression, in the argument to the package macros, see the
+\hyperlink{useofcount}{use of count section} in \autoref{sec:inputs}.
+
+Some of these macros are extended by \xintfracname to accept fractions on input,
+and, generally, to output a fraction. But this means that additions,
+subtractions, multiplications output fractions and not integers; to guarantee
+the integer format on output when the inputs are integers, the original
+integer-only macros \csa{xintAdd}, \csa{xintSub}, \csa{xintMul} remain available
+under the names \csa{xintiAdd}, \csa{xintiSub}, \csa{xintiMul}. Even the
+original integer-only macros may now accept fractions on input as long as they
+are integers in disguise; they still produce on output integers without any
+forward slash mark nor trailing |[n]|. On the other hand macros such as
+|\xintAdd| will output fractions |A/B[n]|, with |B| present even if its value is
+one. To remove this unit denominator and convert the |[n]| part into explicit
+zeros, one has \csbxint{Num} (if one is certain to deal with an integer; see
+also \csbxint{PRaw}). This is mandatory when the computation result is fetched
+into a context where \TeX{} expects a number (assuming it does not exceed
+@2^31@). See the also the \xintfracname \hyperref[sec:frac]{documentation}
+for more information on how macros of \xintname are modified after loading
+\xintfracname (or \xintexprname).
+
+
+% Package \xintname also provides some general macro programming or token
+% manipulation utilities (expandable as well as non-expandable), which are
+% described in the next section (\autoref{sec:tools}).

+\subsection{\csbh{xintRev}} \label{xintRev}
+
+\csa{xintRev\n} will revert the order of the digits of the number,
+keeping the optional sign. Leading zeros
+resulting from the operation are not removed (see the
+\csa{xintNum} macro for this). This macro and all other
+macros dealing with numbers first expand `fully' their arguments.

+ {=\xintLen{-12345678901234567890123456789}}} Extended by \xintfracname to
+fractions: the length of |A/B[n]| is the length of |A| plus the length of |B|
+plus the absolute value of |n| and minus one (an integer input as |N| is
+internally represented in a form equivalent to |N/1[0]| so the minus one means
+that the extended \csa{xintLen}
+behaves the same as the original for integers).
+\centeredline{|\xintLen{-1e3/5.425}|\digitstt
+ {=\xintLen{-1e3/5.425}}}
+The length is computed on the |A/B[n]| which would have been returned by
+\csbxint{Raw}: |\xintRaw {-1e3/5.425}|\digitstt{=\xintRaw {-1e3/5.425}}.
+
+Let's point out that the whole thing should sum up to
+less than circa @2^{31}@, but this is a bit theoretical.

+|\xintLen| is only for numbers or fractions. See \csbxint{Length} for counting
+tokens (or rather braced groups), more generally.

+\csa{xintPow\n\x} returns |N^x|. When |x| is zero, this is 1. If |N| is zero and
+|x<0|, if \verb+|N|>1+ and |x<0| negative, or if \verb+|N|>1+ and |x>999999999|,
+then an error is raised. |2^999999999| has \np{301029996} digits; each exact
+multiplication of two one thousand digits numbers already takes a few seconds,
+so needless to say this bound is completely irrealistic. Already |2^9999| has
+\np{3010} digits,\footnote{on my laptop |\string\xintiPow \{2\}\{9999\}|
+ obtains all |3010| digits in about ten or eleven seconds. In contrast, the
+ float versions for
+ |8|, |16|, |24|, or even more significant figures, do their jobs in circa one
+ hundredth of a second (|1.08b|). This is done without |log|/|exp| which are
+ not (yet?) implemented in \xintfracname. The \LaTeX3
+ \href{http://www.ctan.org/tex-archive/macros/latex/contrib/l3kernel}{l3fp}
+ does this with |log|/|exp| and is ten times faster (|16| figures only).} so I
+should perhaps lower the bound to |99999|.
+
+Extended by \xintfracname to fractions (\csbxint{Pow}) and also to floats
+(\csbxint{FloatPow}). Negative
+exponents do not then cause errors anymore. The float version is able to deal
+with things such as

+\subsection{\csbh{xintFac}}\label{xintiFac}
+
+\csa{xintFac\x} returns the factorial. It is an error if the
+argument is negative or at least @10^6@. It is not recommended to
+launch the computation of things such as @100000!@, if you need
+your computer for other tasks. Note that the argument is of the |x| type, it
+must obey the \TeX{} bounds, but on the other hand may involve count registers
+and even arithmetic operations as it will be completely expanded inside a
+|\numexpr|.
+
+With \xintfracname loaded, the macro also
+accepts a fraction as argument, as long as this fraction turns out to be an

+\subsection{\csbh{xintDivision}}\label{xintDivision}
+
+\csa{xintDivision\n\m} returns |{quotient Q}{remainder R}|. This
+is euclidean division: |N = QM + R|, |0|${}\leq{}$\verb+R < |M|+. So the
+remainder is always non-negative and the formula |N = QM + R|
+always holds independently of the signs of |N| or |M|. Division by
+zero is an error (even if |N| vanishes) and returns |{0}{0}|.
+
+This macro is integer only (with \xintfracname loaded it accepts
+fractions on input, but they must be integers in disguise) and not to be
+confused with the \xintfracname macro \csbxint{Div} which divides one

+\subsection{\csbh{xintDSL}}\label{xintDSL}

+\csa{xintDSL\n} is decimal shift left, \emph{i.e.} multiplication

+
+\subsection{\csbh{xintDSR}}\label{xintDSR}
+
+\csa{xintDSR\n} is decimal shift right, \emph{i.e.} it removes the last digit
+(keeping the sign), equivalently it is the closest integer to |N/10| when
+starting at zero.
+
+\subsection{\csbh{xintDSH}}\label{xintDSH}
+
+\csa{xintDSH\x\n} is parametrized decimal shift. When |x| is
+negative, it is like iterating \csa{xintDSL} \verb+|x|+ times
+(\emph{i.e.} multiplication by @10^{-@|x|@}@). When |x| positive,
+it is like iterating \csa{DSR} |x| times (and is more efficient), and for a
+non-negative |N| this is thus the same as the
+quotient from the euclidean division by |10^x|.
+
+\subsection{\csbh{xintDSHr}, \csbh{xintDSx}}\label{xintDSHr}\label{xintDSx}
+{\small New in release |1.01|.\par}
+
+\csa{xintDSHr\x\n} expects |x| to be zero or positive and it returns
+then a value |R| which is correlated to the value |Q| returned by
+\csa{xintDSH\x\n} in the following manner:
+\begin{itemize}
+\item if |N| is
+ positive or zero, |Q| and |R| are the quotient and remainder in
+ the euclidean division by |10^x| (obtained in a more efficient
+ manner than using \csa{xintDivision}),
+\item if |N| is negative let
+ |Q1| and |R1| be the quotient and remainder in the euclidean
+ division by |10^x| of the absolute value of |N|. If |Q1|
+ does not vanish, then |Q=-Q1| and |R=R1|. If |Q1| vanishes, then
+ |Q=0| and |R=-R1|.
+\item for |x=0|, |Q=N| and |R=0|.
+\end{itemize}
+So one has |N = 10^x Q + R| if |Q| turns out to be zero or
+positive, and |N = 10^x Q - R| if |Q| turns out to be negative,
+which is exactly the case when |N| is at most |-10^x|.
+
+
+\csa{xintDSx\x\n} for |x| negative is exactly as
+\csa{xintDSH\x\n}, \emph{i.e.} multiplication by @10^{-@|x|@}@.
+For |x| zero or positive it returns the two numbers |{Q}{R}|
+described above, each one within braces. So |Q| is
+\csa{xintDSH\x\n}, and |R| is \csa{xintDSHr\x\n}, but computed
+simultaneously.

+
+\csa{xintDecSplit\x\n} cuts the number into two pieces (each one within a
+pair of enclosing braces). First the sign if present is \emph{removed}.
+Then, for |x| positive or null, the second piece contains the |x| least
+significant digits (\emph{empty} if |x=0|) and the first piece the remaining
+digits (\emph{empty} when |x| equals or exceeds the length of |N|).
+Leading zeros in the second piece are not removed. When |x| is negative
+the first piece contains the \verb+|x|+ most significant digits and the
+second piece the remaining digits (\emph{empty} if @|x|@ equals or exceeds
+the length of |N|). Leading zeros in this second piece are not removed.
+So the absolute value of the original number is always the concatenation
+of the first and second piece.
