Sam Cappleman-Lynes	e520bdad0d	Add scalar multiplication to BigUint, BigInt ... BigUint and BigInt can now be multiplied by a BigDigit, re-using the same buffer for the output, thereby reducing allocations and copying.	2017-06-28 14:02:45 +01:00
Eduardo Pinho	61cfdc37b3	BigInt two's complement adjustments ... - rename `_twos_complement_` methods to just `_signed_` - make `from_` variants take &[u8] - refactor helper functions twos_complement (they take byte slice but use a generic function underneath) - fix issues in `to_signed_` functions (only two's complement negative numbers; perform byte extension where needed) - add tests to `to_signed_` methods	2017-06-18 01:42:56 +01:00
Eduardo Pinho	1660590125	Add BigInt 2's complement conversions ... - add methods `from_twos_complement_bytes_le`, `from_twos_complement_bytes_be`, `to_twos_complement_bytes_le`, and `to_twos_complement_bytes_be` to `BigInt`. - add respective tests	2017-06-16 17:58:04 +01:00
