CTAN up­date: xint

Jean-Fran?ois Burnol sub­mit­ted an up­date to the xint pack­age. Ver­sion num­ber: 1.2g 2016-03-19 Li­cense type: lp­pl1.3 Sum­mary de­scrip­tion: Ex­pand­able op­er­a­tions on long num­bers An­nounce­ment text:
List se­lec­tors [L][n], [L][a:b], in ex­pres­sions are faster. And items are counted start­ing at zero, not one ([L][a:b] al­ready fol­lowed ex­actly Python slic­ing rules). The iter key­word's mean­ing has changed, new one as­so­ci­ated with rseq, for­mer one which is as­so­ci­ated to rrseq re­named to iterr. The float op­er­a­tions with large pre­ci­sion han­dle small in­puts faster. The doc­u­men­ta­tion has an ex­am­ple of us­ing iter to im­ple­ment ex­pand­ably the Brent-Salamin al­go­rithm for dig­its of Pi. See CHANGES.{pdf,html} for more.

xint – Ex­pand­able op­er­a­tions on long num­bers

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 , , or (a pri­ori) any other macro for­mat built upon .
