Num.to_bytes - OverflowError: int too big to convert

Question

In order to convert -10947726235 into byte array I ran:

Num = -10947726235
ByteArray = Num.to_bytes(4, byteorder='little', signed=True)

I got:

OverflowError: int too big to convert

Can you please advise?

Answer 1

Four bytes can only represent a negative number of -2 billion-ish or lower.

>>> int.from_bytes(bytes([0,0,0,0x80]), 'little', signed=True)
-2147483648

You need five bytes or more to represent your number:

>>> Num = -10947726235
>>> Num.to_bytes(5, 'little', signed=True).hex(' ')
'65 f4 76 73 fd'
