How do I convert a Python float to a hexadecimal string in python 2.5? Nonworking solution attached

Question

What I really need to do is to export a floating point number to C with no precision loss.

I did this in python:

import math
import struct
x = math.s

If you're targeting a little-endian architecture,

>>> s = struct.pack('>> ''.join('%.2x' % ord(c) for c in s)
'cd3b7f669ea0f63f'

if big-endian, use '>d' instead of . In either case, this gives you a hex string as you're asking for in the question title's, and of course C code can interpret it; I'm not sure what those two ints have to do with a "hex string".
