[CTAN Announcements]

Jean-François Burnol submitted an update to the

                xint

package.

License type: lppl1.3

Summary description: Expandable operations on long numbers

Bug fixes

-   squaring macro \xintSqr from xintfrac.sty was broken due to a
    misspelled sub-macro name. Dates back to 1.1 release of 2014/10/28
    :-((.

-   1.2c's fix to the subtraction bug from 1.2 introduced another bug,
    which in some cases could create leading zeroes in the output, or
    even worse. This could invalidate other routines using subtractions,
    like \xintiiSquareRoot.

Improvements and new features

-   functions binomial, pfactorial and factorial in both integer and
    float versions.

-   faster implementation and increased accuracy of float power macros.

-   faster implementation of both integral and float square root macros.

-   the float square root achieves _correct_ (aka _exact_) rounding in
    arbitrary precision.

-   modified behaviour for the \xintPFloat macro, used by
    \xintthefloatexpr to prettify its output. It now opts for decimal
    notation if and only if scientific notation would use an exponent
    between -5 and 5 inclusive. The zero value is printed 0. with a dot.

-   the documentation offers a more precise (and accurate) discussion of
    floating point issues.

-   various under-the-hood code improvements; the floatexpr operations
    are chained in a faster way, from skipping some unneeded parsing on
    results of earlier computations. The absence of a real inner data
    structure for floats (incorporating their precisions, for one) is
    however still a bit hair rising: currently the lengths of the
    mantissas of the operands are computed again by each float macro or
    expression operation.

-   renewed desperate efforts at improving the documentation by random
    shuffling of sections and well thought additions; cuts were
    considered and even performed.
