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"))`

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))`

			`il = int.from_bytes(b, "little")`
			`ib = int.from_bytes(b, "big")`
			`print(il)`
			`print(ib)`
			`print(il.to_bytes(20, "little"))`
tests/basics: Add tests for int.from_bytes when src has trailing zeros. The trailing zeros should be truncated from the converted value. 2017-04-24 22:07:02 -04:00
