# Release 0.2.2
|
|
|
|
|
|
|
|
|
|
- [Casting from floating point to integers now returns `None` on overflow][52],
|
|
|
|
|
avoiding [rustc's undefined behavior][rust-10184]. This applies to the `cast`
|
|
|
|
|
function and the traits `NumCast`, `FromPrimitive`, and `ToPrimitive`.

# Release 0.2.1
|
|
|
|
|
|
|
|
|
|
- [The new `FloatCore` trait][32] offers a subset of `Float` for `#![no_std]` use.
|
|
|
|
|
[This includes everything][41] except the transcendental functions and FMA.
|
|
|
|
|
- [The new `Inv` trait][37] returns the multiplicative inverse, or reciprocal.
|
|
|
|
|
- [The new `Pow` trait][37] performs exponentiation, much like the existing `pow`
|
|
|
|
|
function, but with generic exponent types.
|
|
|
|
|
- [The new `One::is_one` method][39] tests if a value equals 1. Implementers
|
|
|
|
|
should override this method if there's a more efficient way to check for 1,
|
|
|
|
|
rather than comparing with a temporary `one()`.

# Release 0.2.0
|
|
|
|
|
|
2018-02-07 04:49:17 +00:00
|
|
|
- **breaking change**: [There is now a `std` feature][30], enabled by default, along
|
2018-02-07 01:01:31 +00:00
|
|
|
with the implication that building *without* this feature makes this a
|
2018-03-01 22:20:57 +00:00
|
|
|
`#![no_std]` crate.
|
2018-02-07 01:01:31 +00:00
|
|
|
- The `Float` and `Real` traits are only available when `std` is enabled.
|
|
|
|
|
- Otherwise, the API is unchanged, and num-traits 0.1.43 now re-exports its
|
|
|
|
|
items from num-traits 0.2 for compatibility (the [semver-trick]).

# Release 0.1.42
|
|
|
|
|
|
|
|
|
|
- [num-traits now has its own source repository][num-356] at [rust-num/num-traits][home].
|
|
|
|
|
- [`ParseFloatError` now implements `Display`][22].
|
|
|
|
|
- [The new `AsPrimitive` trait][17] implements generic casting with the `as` operator.
|
|
|
|
|
- [The new `CheckedShl` and `CheckedShr` traits][21] implement generic
|
|
|
|
|
support for the `checked_shl` and `checked_shr` methods on primitive integers.
|
|
|
|
|
- [The new `Real` trait][23] offers a subset of `Float` functionality that may be applicable to more
|
|
|
|
|
types, with a blanket implementation for all existing `T: Float` types.
