Jean-François Burnol submitted an update to the

xint

package.

Version number: 1.09j License type: lppl

Summary description: Expandable operations on long numbers

Announcement text: ----------------------------------------------------------------------

1.09j 2014/01/09

* The core division routines have been re-written for some (limited) efficiency gain, more pronounced for small divisors. As a consequence, the computation with the algorithm given in the user manual of one thousand digits of Pi is three times faster. Some other small improvements elsewhere.

* A new macro xintXTrunc is designed to produce thousands or even tens of thousands of digits of the decimal expansion of a fraction. Although completely expandable it has its use limited to inside an |edef|, |write|, |message|, dots. It can thus not be nested as argument to another package macro.

* xintexpr.. elax can now be used inside an edef without the xintthe prefix converting the internal format into explicit digit tokens; it will expand completely and inhibit the error message about a missing xintthe. This can significantly speed up the use of xintexpr in a non-expandable contexts, when dealing with numbers having hundreds of digits.

Notice that contrarily to umexpr for which he or umber is necessary not only to print but also to trigger the computation, xintthe is only needed for the printing step (previously xintexpr was already fully expandable under omannumeral-`0).

* bug-fix: |1.09i| did an unexplainable change to XINT_infloat_zero which broke the floating point routines for vanishing operands :-((

The first two pages of the user manual give a much clearer view of the aims and abilities of the package. The manual has more of these tremendous applications my (singleton) user base enjoy so much!
