Jean-François Burnol submitted an update to the
xint
package.
Version number: 1.2d 2015-11-18 License type: lppl1.3
Summary description: Expandable operations on long numbers
Announcement text: ---------------------------------------------------------------------- - bugfix in xintcore: release 1.2c had inadvertently broken the xintiiDivRound macro.
- the function definitions done by xintdeffunc et al., as well as the macro declarations by xintNewExpr et al. now have only local scope.
- tacit multiplication applies to more cases, for example (x+y)z, and always ties more than standard * infix operator, e.g. x/2y is like x/(2*y).
Here is an example (which I forgot to include in the 1.2c announcement) combining the two items above:
xintdeffloatfunc rump(x,y):=333.75y^6+x^2(11x^2y^2-y^6-121y^4-2)+5.5y^8+x/2y;
One can then evaluate xintthefloatexpr rump(77617,33096) elax, but will be suprprised by the result if not using at least 37 decimal digits of precision...
Some documentation enhancements, particularly in the chapter on xintexpr.sty, and also in the code source comments. ----------------------------------------------------------------------
