Greetings

I'm trying to arrange a process of saving double or single precison numbers to a binary file for later access via C or VB code. Another factor is that the file has to be saved either in little endian or big endian mode.

I've found this code:

open(my $out, '>:raw', 'sample.bin') or die "Unable to open: $!";
print $out pack('s<',255) ;
close($out);

[download]

which is supose to save the value 255 as a short variable. Can someone please help me to create a process to save a sequence of 2 or 3 numbers, either in single or double precision, and either in big or little endian? I supose that the sequencial part is made by the append operator (my $out, '>>:raw', 'sample.bin'), and the double or single precision with a letter diferent of 's' (maybe 'd'?). As for the little/big endian, I have no idea...

Kind regards,

Kepler
