tests/basic: Split tests into working with small ints and not working. Tests which don't work with small ints are suffixed with _intbig.py. Some of these may still work with long long ints and need to be reclassified later. 2017-03-03 16:13:27 -05:00			`print((2**64).to_bytes(9, "little"))`
py/objint: Support "big" byte-order in int.to_bytes(). 2017-06-14 23:56:21 -04:00			`print((2**64).to_bytes(9, "big"))`

tests: Add test for int.from_bytes() for arbitrary-precision integer. This test works only for MICROPY_LONGINT_IMPL == MICROPY_LONGINT_IMPL_MPZ and needs a way of skipping in other cases. 2017-01-21 12:15:31 -05:00			`b = bytes(range(20))`
