    Jean-Frantois Burnol submitted an update to the

    zeckendorf

    package.

    Version number: 0.9d 2025-11-16
    License type: lppl1.3c

    Summary description: Knuth Fibonacci multiplication, Zeckendorf and Bergman representations of big integers

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


    An effort has been made to document completely the underlying mathematical algorithms. The interactive interface has been extended with hexadecimal notation for Zeckendorf and Bergman representations. There are some breaking changes, check the PDF.

    This adds many new features and has some breaking changes due to
    renamings, not listed here.
    =20
    - It is not \xintiieval but \xinteval's syntax which is now
    extended.
    =20
    - Variables phi and psi are defined and one can do algebra with +,
    -, *, and ^ on them in Q(phi).
    =20
    - The Bergman phi-representation is added for elements of
    Z[phi] in particular for integers.
    =20
    - The $ character doing the Knuth Fibonacci multiplication on
    positive integers now uses the (more efficient) Arnoux formula.
    The $$ computes out of deference according to the Knuth formula.
    =20
    - The PDF documentation section on the mathematical background has
    been extended and includes bibliographical references.
    =20
    - The interactive interface integrates all novelties.
