Jean-François Burnol submitted an update to the xint package. Version number: 1.4m 2022-06-10 License type: lppl1.3c Summary description: Expandable operations on long numbers Announcement text: -- - compatibility with miniltx (bugfix to resolve an infinite loop which appeared at 1.4l, but the situation was buggy even before). - documentation improvements, in particular each instance of a macro in the code source is linked to the place where it was first defined. Back and forth cross-references from the implementation to the user documentation are active in the file xint-all.pdf (not included, see README.md for the simple build instructions starting with xint.dtx). Some removals of long deprecated macros had been already acted when the miniltx compatibility bug surfaced so with hesitation I decided not to revert them.

1.4b (2020/02/25)
* Added:
- functions zip() and flat()
- chaining of comparison operators
- customizability of the "e" separator of mantissas
and exponents in output of \xintfloateval
* Fixed:
- \xintieval{[D]...} with a negative D (a 1.4a feature) used
erroneously a catcode 12 "e" in output, which moreover was
immune to customization
* Announced:
- long deprecated &, |, and = will be removed at next
major release, use &&, || and ==.
- \thexintexpr et al. will be removed at next major
release, use \xinttheexpr or directly \xintexpr et al. as
since 1.4 they can be used in typesetting flow.
- power operators ** and ^ will turn from left to right
associative at next major release. This matches with
Python and l3fp.
* Various documentation fixes and improvements.

License: lppl1.3c
Summary description: Expandable operations on long numbers
Announcement text:
--
This is a major release with some breaking changes.
Selected highlights:
- The \expanded primitive (TeXLive 2019) is required. Its usage
has allowed dropping formerly used \csname techniques. There is
no more impact on the string pool memory.
- Square brackets [...] are now associated with actual nested
structures. For example \xinteval{1, [2, [3, 4]], 5} produces
1, [2, [3, 4]], 5 (recall this is free bloatware).
- Scalar operations on one-dimensional "lists" (which as it turned
out matched the NumPy "broadcasting" concept) are provisorily
dropped. Alternative syntax exists to rescue old documents.
- Operations on nested lists are inspired from NumPy's.
Currently, nested (basic) slicing and indexing is implemented.
But the step parameters are not. The broadcasting of scalar
operations is not yet implemented but the user can define
"universal functions", i.e. functions operating on all leaves of
the data. Our structures have leaves at arbitrary varying
depths, they are not necessarily hyperrectangular like NumPy's.
Constructors are provided, for example ndmap() maps a function
on all Cartesian n-uples built from items (at top level) of n
given lists.
- Variables in function declarations may be multi-letter words.
- The last positional variable name may be prefixed with a * as in
Python to signal it is a "nut-ple" receiving all arguments of
the function calls beyond the first positional ones ("variadic"
argument). Generally speaking, * is the unpacking operator.
- ... quite a few more features. See CHANGES.html and xint.pdf.

The dependency on xintgcd is removed. - xintexpr: \xinteval, \xintieval, \xintiieval, and \xintfloateval as synonyms to \xintthexpr...\relax etc..., but with the (comma-separated) expression as a usual braced macro argument. Attention: these names were formerly used with some other (barely documented) meanings, for which \xintexpro, \xintiexpro, etc... are now used. - xintexpr: \xintifsgnexpr, \xintifsgnfloatexpr, \xintifsgniiexpr, \xintunassignexprfunc, \xintunassigniiexprfunc, \xintunassignfloatexprfunc, isone() and isint(). Bug fix - xintcore, xintexpr : division in \xintiiexpr was broken for a zero dividend and a one-digit divisor (e.g. 0//7) since 1.2p due to a bug in \xintiiDivMod for such arguments. The bug was signaled (thanks to Kpym for report) and fixed shortly after 1.3c release of June 2018 but I then **completely forgot** to upload a bugfix release to CTAN at that time, apologies for that.

Maintenance release.
- The underscore character _ is accepted by the xintexpr parsers
as a digit separator. Example:
\xinttheiiexpr 123_456_789 * __ \relax
It is not allowed as _first_ character of a number, as it would
then be mis-interpreted as the start of a possible variable
name. Only expressions handle it (the space character can also
separate digits there), not macros.
The LaTeX package bnumexpr will also accept the underscore as
digit separator in its upcoming release.
- Some refactoring in xintcore for some small efficiency gains.
- Some macros were not robust against arguments whose expansion
looks forward for some termination (e.g. \number\mathcode`\-),
and many more were broken if the inputs used a non-terminated
\numexpr, e.g. \xintAdd{\the\numexpr1}{2}. The user manual never
said this was legal input, but it was slightly inconvenient.
Most macros have now been made robust against such non properly
terminated inputs.
In expressions though, a \numexpr swallowing the ending \relax
is definitely still to be avoided, as the parser absolutely
needs to hit against such a token at some point.
- A few minor bugfixes, see CHANGES.pdf or CHANGES.html for the
details.

Version number: 1.2k 2017-01-06 License type: lppl1.3 Summary description: Expandable operations on long numbers Announcement text: -- - The xintfrac.sty floating point macros since 1.2f round their arguments to the target precision P before further processing. This rounding is now exact (aka correct) in all cases, even with fractions having long numerators and denominators. This change has little influence on float expressions, as the \xintfloatexpr parser handles there the / symbol as an operator hence it does not (except for special constructs) get to see fractions as such. - Half-integer powers A^x (only available in float expressions, not via macros) proceed by an integer power and then a square-root extraction: the 1.2f implementation did the latter on an already rounded value, 1.2k keeps some of the guard digits to make the computed value Z closer to the exact one: a difference of less than 0.52 ulp(Z) is guaranteed in all cases. - Macro \xintnewdummy is made a public one, it serves to declare additional letters as dummy variables in expressions. This is for Unicode engines, mainly, as all Latin letters are already predefined to act as such.

`\xintdeffunc` is not usable. Indeed, one can not currently do:
\xintdeffunc foo(x):= add(i^2, i=1..x);
in part because the dummy variable range is not explicitely known
as it depends on the variable x. But now one can do:
\xintNewFunction {foo}[1]{add(i^2, i=1..#1)}
and the full syntax is allowed in the replacement text because its
actual parsing is delayed to the time where `foo()` will actually
be used. The arguments may then be numerical, or dummy variables,
or sub-expressions etc... `foo()` is then like a genuine function
for the three parsers `\xintexpr`, `\xintiiexpr`, `\xintfloatexpr`.
This is very different from `\xintdeffunc` and the closely related
`\xintNewExpr` which attempt to parse expressions (either with
variables or macro parameters) and convert them in advance into
(possibly very complicated) nested macro calls.
Side note: after three years of strict obedience to xint prefix,
`\thexintexpr`, etc... are provided as synonyms to `\xinttheexpr`,
etc...

CTAN update: xint
Jean-François Burnol submitted an update to the
xint
package.

License type: lppl1.3
Summary description: Expandable operations on long numbers
Announcement text:
--
List selectors [L][n], [L][a:b], in expressions are faster. And
items are counted starting at zero, not one ([L][a:b] already
followed exactly Python slicing rules). The iter keyword's meaning
has changed, new one associated with rseq, former one which is
associated to rrseq renamed to iterr. The float operations with
large precision handle small inputs faster.
The documentation has an example of using iter to implement
expandably the Brent-Salamin algorithm for digits of Pi.
See CHANGES.{pdf,html} for more.

Bug fixes
- squaring macro \xintSqr from xintfrac.sty was broken due to a
misspelled sub-macro name. Dates back to 1.1 release of 2014/10/28
:-((.
- 1.2c's fix to the subtraction bug from 1.2 introduced another bug,
which in some cases could create leading zeroes in the output, or
even worse. This could invalidate other routines using subtractions,
like \xintiiSquareRoot.
Improvements and new features
- functions binomial, pfactorial and factorial in both integer and
float versions.
- faster implementation and increased accuracy of float power macros.
- faster implementation of both integral and float square root macros.
- the float square root achieves _correct_ (aka _exact_) rounding in
arbitrary precision.
- modified behaviour for the \xintPFloat macro, used by
\xintthefloatexpr to prettify its output. It now opts for decimal
notation if and only if scientific notation would use an exponent
between -5 and 5 inclusive. The zero value is printed 0. with a dot.
- the documentation offers a more precise (and accurate) discussion of
floating point issues.
- various under-the-hood code improvements; the floatexpr operations
are chained in a faster way, from skipping some unneeded parsing on
results of earlier computations. The absence of a real inner data
structure for floats (incorporating their precisions, for one) is
however still a bit hair rising: currently the lengths of the
mantissas of the operands are computed again by each float macro or
expression operation.
- renewed desperate efforts at improving the documentation by random
shuffling of sections and well thought additions; cuts were
considered and even performed.

CTAN update: xint
Jean-François Burnol submitted an update to the xint package. Version number: 1.2d 2015-11-18 License type: lppl1.3 Summary description: Expandable operations on long numbers Announcement text: -- - bugfix in xintcore: release 1.2c had inadvertently broken the \xintiiDivRound macro. - the function definitions done by \xintdeffunc et al., as well as the macro declarations by \xintNewExpr et al. now have only local scope. - tacit multiplication applies to more cases, for example (x+y)z, and always ties more than standard * infix operator, e.g. x/2y is like x/(2*y). Here is an example (which I forgot to include in the 1.2c announcement) combining the two items above: \xintdeffloatfunc rump(x,y):=333.75y^6+x^2(11x^2y^2-y^6-121y^4-2)+5.5y^8+x/2y; One can then evaluate \xintthefloatexpr rump(77617,33096)\relax, but will be suprprised by the result if not using at least 37 decimal digits of precision... Some documentation enhancements, particularly in the chapter on xintexpr.sty, and also in the code source comments. -- This package is located at http://mirror.ctan.org/macros/generic/xint More information is at http://www.ctan.org/pkg/xint We are supported by the TeX Users Group http://www.tug.org .

This bugfix release corrects a bad bug which was introduced in 1.2
from 2015/10/10: the \xintexpr parser mistook numbers like 0.01 for
zero !
The developer apologizes. Please upgrade if you installed recently
released 1.2.
See CHANGES.{pdf|html} for a few minor changes (some added macros).

CTAN update: xint
Jean-François Burnol submitted an update to the xint package. Version number: 1.2 2015-10-10 License type: lppl1.3 Summary description: Expandable operations on long numbers Announcement text: -- - the basic arithmetic implemented in xintcore has been entirely rewritten. The mathematics remains the elementary school one, but the TeX implementation achieves higher speed (except, regarding addition/subtraction, for numbers up to about thirty digits), the gains becoming quite significant for numbers with hundreds of digits. - the inputs must have less than 19959 digits. But computations with thousands of digits take time. - a previously standing limitation of the expression parsers to numbers with less than 5000 digits has been lifted. - new macro for computing the factorials (of integers) as floating point numbers, to which the ! postfix operator inside \xintfloatexpr is mapped. - the macros \xintAdd, \xintSub, ..., now require package xintfrac. With only xintcore or xint loaded, one _must_ use \xintiiAdd, \xintiiSub, ..., or \xintiAdd, \xintiSub, etc... - an effort at randomly shuffling around various pieces of the documentation has been done. -- This package is located at http://mirror.ctan.org/macros/generic/xint More information is at http://www.ctan.org/pkg/xint We are supported by the TeX Users Group http://www.tug.org .
