License type: lppl
Summary description: Expandable operations on long numbers
Announcement text:
Release 1.09m: * xintcfrac: \xintFGtoC finds the initial partial quotients which are common to two decimal numbers (or fractions): \xintFGtoC{3.141592653}{3.141592654} -> {3}{7}{15}{1} \xintFGtoC{3.141592653589}{3.141592653590} -> {3}{7}{15}{1}{292}{1}{1}{1}{2}{1} \xintGGCFrac typesets generalized continued fractions, not assuming that the coefficients are numeric quantities. * xinttools: \xintKeep keeps the first N or last N elements of a list (sequence of braced items); \xintTrim cuts out either the first N or the last N elements from a list. Some other minor changes.

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.
