CTAN Update: xint
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
Loading xintexpr provides \xinteval and \xintfloateval.
\xintfloateval evaluates numerical expressions. The floating point precision defaults to 16 decimal digits and can be set by user. Trigonometry, exponential and logarithms are implemented up to a maximal precision of 62 decimal digits.
\xinteval computes exactly with integers, fractions, and decimal numbers or numbers in scientific notation. Note though that multiplying two floating point numbers will about double the number of digits, and so on, because the algebra is done exactly.
Both are compatible with expansion-only context.
Loading xintexpr imports automatically various other modules that it depends upon. Among them:
- xinttools: utilities such as expandable and non-expandable loops,
- xint: macros implementing in particular the basic operations on arbitrarily long integers,
- xintbinhex: conversions between decimal and binary, octal, or hexadecimal bases for arbitrarily long integers,
- xintfrac: macros implementing in particular the basic operations on arbitrarily large fractions, decimal numbers, or numbers in scientific notation.
Further modules of independent interest include xintgcd, xintseries and xintcfrac.
You can use xintexpr (and the other components) with LaTeX (via \usepackage) or also with Plain TeX, OpTeX, or ConTeXt (via \input xintexpr.sty).
All the components are documented in the file xint.pdf, which also contains the commented source code.
