perfect for numpy, but at this point I don't have a numpy dependency
(very unusual for my code!). Anyone know a pure-python way to get it?
It seems I should be able to do something like:
struct.pack("d",-3.4)[0] & Something
but I'm not sure what "Something" is, and it would be endian-dependent,
wouldn't it?
thanks,
