Summary description: Knuth multiplication and Zeckendorf representations of big integers

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

This package adds to \xintiieval’s syntax the $ character as infix operator computing the Knuth multiplication of positive integers. It adds functions to this syntax, as well as macros for use without it, to work with Fibonacci numbers and Zeckendorf representations.

It can be used either as a LaTeX package, or with Plain eTeX, or on the command line in an interactive session using eTeX.

Being based upon xintexpr, it allows to compute with "arbitrarily" big integers.
