Jean-François Burnol submitted an update to the
xint
package.
Version number: 1.2l 2017-07-26
License type: lppl1.3c
Summary description: Expandable operations on long numbers
Announcement text:
Maintenance release. - The underscore character _ is accepted by the xintexpr parsers as a digit separator. Example: \xinttheiiexpr 123_456_789 * 1111_2222_3333 \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.

xint – Expandable arbitrary precision floating point and integer operations
The xint bundle main modules are:
- xinttools
- utilities of independent interest such as expandable and non-expandable loops,
- xintcore
- expandable macros implementing addition, subtraction, multiplication, division, and powers for arbitrarily long integers,
- xint
- extension of xintcore,
- xintfrac
- extends the scope of xint to decimal numbers, to numbers using scientific notation and also to (exact) fractions,
- xintexpr
- provides expandable parsers of numeric expressions using the standard infix notations, parentheses, built-in functions, user definable functions and variables (and more ...) which do either exact evaluations (also with fractions) or floating point evaluations under a user chosen precision.
Further modules of the bundle are:
xintkernel (support macros for all the bundle constituents),
xintbinhex (conversion to and from hexadecimal and binary bases),
xintgcd (provides gcd() and lcm() functions to xintexpr),
xintseries (evaluates numerically partial sums of series and
power series with fractional coefficients), and
xintcfrac (dedicated to the computation and display of continued fractions).
All computations are compatible with expansion-only context.
The packages may be used with Plain TeX, LaTeX, or (a priori) any other macro format built upon TeX.
