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.
A BigDigit can be subtracted from a BigUint - this is one of several
operations being implemented to allow scalar operations on BigInt and
BigUint across the board.
A BigDigit can be added to a BigUint - this is one of several
operations being implemented to allow scalar operations on BigInt and
BigUint across the board.
- 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
Revert "Auto merge of #296 - vks:no_std, r=cuviper"
This reverts commit 8b5d4ac24e, reversing
changes made to ef752e4687.
See #297 -- it's a breaking change to feature-gate existing APIs.
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.

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`.
Refs #216.

Get the default hasher indirectly
`DefaultHasher` wasn't stable until 1.13, at which point all the other
hashers were deprecated, so it's not easy for us to name a hasher type to
use for testing. However, `RandomState` has been stable since 1.7, and it
implements `BuildHasher` that has a `Hasher` associated type.
