    4.78: How do I pack arrays of doubles or floats for XS code?

    The arrays.h/arrays.c code in the "PGPLOT" module on CPAN does just
    this. If you're doing a lot of float or double processing, consider
    using the "PDL" module from CPAN instead--it makes number-crunching
    easy.

    See <http://search.cpan.org/dist/PGPLOT> for the code.

    are not necessarily experts in every domain where Perl might show up,
    so please include as much information as possible and relevant in any
    corrections. The perlfaq-workers also don't have access to every
    operating system or platform, so please include relevant details for
    corrections to examples that do not work on particular platforms.
    Working code is greatly appreciated.
