Hi David,
Thanks very much for your code, I will try it when I get home at the end of
the week although I only have little endian Intell chips. I will have to
look around for others. Btw, are there still chips storing big endian
paired in two bytes? So your example number would become 0x23, 0x01, 0x67,
0x45 ?
Thanks again,
Marcel

Hi Marcel,
With regard to checking for endianess. I don't think there's anything built
in NativeCall that directly determines this, but hopefuly the following
should do it, without resorting to a C compiler.
use NativeCall;
sub little-endian returns Bool {
my $i = CArray[uint32].new: 0x01234567;
my $j = nativecast(CArray[uint8], $i);
say sprintf("j[0]:%x j[3]:%x", $j[0], $j[3]);
$j[0] == 0x67;
}
say "little-endian:" ~ little-endian;
I've only tested this on a little endian architecture.

Hi
Thanks for your answer. I was thinking in perl6, I should have been more
explicit. At the moment I am converting Num to a float representation in
my
BSON module and was wondering if there where easier ways and maybe faster
too.
Regards,
Marcel
