CTAN update: xint

the daemon cheerfully reports: > Name of contribution: xint > Author's name: Jean-François Burnol > Package version: 1.03 > Location on CTAN: macros/generic/xint/ > Summary description: Expandable operations on long numbers > License type: lppl > > Announcement text given by the package's contributor: > ---------------------------------------------------------------------- > version 1.03 of xint (2013/04/14) > > The xint bundle has two new components: > xintfrac.sty Expandable operations on fractions > xintseries.sty Expandable partial sums with xint package > > xintfrac.sty extends the macros of xint.sty to apply to > fractions of arbitrary sizes (please don't type in numerators > or denominators with more than 2147483639 digits, if I may ask). > > As with xint.sty, all computations are done in a manner > compatible with expansion-only context. The computations are > always done exactly and when printing a fraction with an > asked-for given number of digits, all digits are exact. > > xintseries.sty provides some basic functionality to compute > partial sums of series or power series. The computations may be > done exactly or with a truncation at a given number of digits > after the decimal point. > > There have been only some changes to the original xint.sty > macros: in particular, the division is a bit faster, and the > multiplication is a bit slower on less than 50 digits numbers as > it now decides by itself what is the probable best order for the > inputs ; this leads to potential significant speed gains when one > of the number is much longer than the other. It was also crucial > for the calculus with fractions as the choice of the best order > can not be guessed in advance. > > The documentation has been revised and enlarged. The traditional > Machin algorithm to compute pi is illustrated. Of course, recall > that this is all done without any memory assignments, purely by > macro expansion, and xintseries is thus no threat to the > computing software industry. > > All components of the xint bundle may be used either with Plain > TeX or with LaTeX. > > Please report bugs to the author. thanks for the upload; i've installed the new version, and updated the catalogue repository. > Users may view the package catalogue entry at > http://www.ctan.org/pkg/xint > or they may browse the package directory at > http://mirror.ctan.org/macros/generic/xint/ Robin Fairbairns For the CTAN team
