Sam Cappleman-Lynes fd87d87db3 Fix normalization in scalar addition 2017-06-29 20:40:54 +01:00
Josh Stone 3f32ad48f4 rational: make sure Hash agrees with Eq 
We can't use a derived `Hash` when we have a manual `Eq`, because we
need to uphold the invariant `a == b` → `h(a) == h(b)`.  Since `Eq`
doesn't require them to be in reduced form, `Hash` also needs to be
normalized.

Sam Cappleman-Lynes 784d26bbf8 Scalar division of a BigUint by a BigDigit 
A BigUint can be divided by a BigDigit - this is one of several
operations being implemented to allow scalar operations on BigInt and
BigUint across the board.

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.

Eduardo Pinho 15f9334955 De-generalize `twos_complement' helper function 2017-06-20 01:31:49 +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

- 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

Homu 681bbf8659 Auto merge of #300 - cuviper:no-default-subcrates, r=cuviper 
Test and fix subcrates with --no-default-features

- The CI script now tests them all with --no-default-features.
- bigint: testing needs rand even when the main feature is disabled.
- rational: gate `FromPrimitive for Ratio<BigInt>` on having bigint.
