objint: Implement int.from_bytes() class method and .to_bytes() method. These two are apprerently the most concise and efficient way to convert int to/from bytes in Python. The alternatives are struct and array modules, but methods using them are more verbose in Python code and less efficient in memory/cycles. 2014-04-08 17:40:58 -04:00			`print((10).to_bytes(1, "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
