Le 21/02/2018 à 14:27, ast a écrit : struct.pack() as advised works fine. Exemple:
>>> import struct
>>> struct.pack(">d", -0.0)
b'\x80\x00\x00\x00\x00\x00\x00\x00'
before I read your answers I found a way
with pickle
>>> import pickle
>>> pickle.dumps(-0.0)[3:-1]
b'\x80\x00\x00\x00\x00\x00\x00\x00'
but struct.pack() is better
Thx
