CTAN update: xint

Date: April 7, 2019 8:27:09 PM CEST
Jean-François Burnol submitted an update to the xint package. Version number: 1.3e 2019-04-05 License type: lppl1.3c Summary description: Expandable operations on long numbers Announcement text:
xintexpr now provides trigonometrical functions (direct and inverse) up to 60 digits of precision, and exponentials and logarithms (via poormanlog package) but for the latter only to about 9 digits of precision. This will be improved in future. The trigonometrical functions are (for the most part) implemented via the high level user interface. Future releases will code them at lower level, for efficiency. For more details, refer to the Recent Changes section of xint.pdf.

xint – Expandable operations on long numbers

The xint bundle main modules are:

utilities of independent interest such as expandable and non-expandable loops,
expandable macros implementing addition, subtraction, multiplication, division, and powers for arbitrarily long integers,
extension of xintcore,
extends the scope of xint to decimal numbers, to numbers using scientific notation and also to (exact) fractions,
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 , , or (a priori) any other macro format built upon .
