CTAN Update: xint

Jean-François Burnol submitted an update to the
xint
package.
Version number: 1.09c
License type: lppl
Summary description: Expandable operations on long numbers
Announcement text:
Release 1.09c adds new features: * bool and togl are two new functions recognized by the \xintexpr parser. They act as in etoolbox boolean expressions (togl requires etoolbox, as it gives the truth value of the named toggle), and may be freely combined using the logic operators &, |, or functions all, any, xor, etc... * new conditional \xintifboolexpr {<expr>}{YES}{NO}, where <expr> is written in the \xintexpr recognized infix syntax, * the (non-expandable) utility \xintApplyInline has been enhanced to be usable in contexts such as alignments where the applied macro may close groups, * \xintFor is a new kind of for loop: it uses #1, #2, #3, #4 rather than macros to represent the (comma separated) list items; e.g. \xintFor #1 in {a,b,c} \do {\textbf{#1}}. Despite not being completely expandable, it is nestable, and usable to generate rows in alignments, as it survives the closing of groups via its replacement text, * \xintSeq expandably generates arithmetic sequences. Some other changes and code improvements, and improved documentation.

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.
