Are long and short ints easy as well? BM> The sprintf() family is your friend. that will only generate text (hex and other formats). he needs pack which does exactly what he wants. read perlpacktut for a tutorial on pack/unpack and then perlfunc -f pack for the reference on it. pack can take a perl float and make a string of the internal representation in either endian order. for some real world examples of doing that, check out the code in Sort::Maker which packs floats into strings and deals with endian issues too. uri -- .signature_stem -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
