    I am also very happy that you got this figured out! I very seldom work with floats.
    In my investigations, I found this:
    use Config; # This should print 8 if on a 64 bit machine... print $Config{nvsize}, " float size in bytes\n";
    Might consider checking that as a sanity check that you are on 64 bit machine. I have no idea how to get Perl to do 64 bit floats on a 32 bit machine - but there is probably a way.
