Hi,
Im implementing a communication protocol in pys60 and i need to convert from signed float (-122.7886577) to hex and from hex to signed float.
How can i convert preserving the signal and the precision?
At this time i can only make the conversion between int and hex.

Tks for help.

hi Marcos, fine ?

when I write network programs I like to use struct module.
With it you have the necessary control like byte order, padding, and so on.
Using struct.pack to format an output buffer is simple. Just check this link:

http://docs.python.org/library/struct.html

import struct
data = struct.pack("f",-123.456)

struct.unpack is used to do the reverse operation (from bytes to python)
