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

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

traits: Introduce std feature

This makes it possible to build `traits` without `std`. For this a new
trait `BasicFloat` was introduced, implementing some basic functionality
that works with `core`. Most notably this is lacking functions like
`cos`, `sin`, etc.

`Float` is not available without `std`.
