Is that a safe BM> assumption? ieee float format is about the only way anyone does floats today. but pack actually doesn't even care about the float format. it just copies the internal float to a place where it can be accessed as a string of bytes (the string slot in the scalar). you can take any byte string you want and unpack back into the float slot. the only restriction is the size and that is usually 8 bytes (a double which is perl's standard float size). pack supports single precision (4 bytes) as well as long doubles if your machine supports them. as for whether this is what the OP wanted, note that he since posted that he is reading perlpacktut for his answers. someone else already posted the pack format needed but i wanted him to rtfm and learn more about pack. uri -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
