41: Various improvements to FloatCore r=vks a=cuviper
- New macros simplify forwarding method implementations.
- `Float` and `Real` use this to compact their implementations.
- `FloatCore` now forwards `std` implementations when possible.
- `FloatCore` now requires `NumCast`, like `Float does.
- New additions to `FloatCore`:
- Constants like `min_value()` -> `f64::MIN`
- Rounding methods `floor`, `ceil`, `round`, `trunc`, `fract`
- `integer_decode` matching `Float`'s
- Fix NAN sign handling in `FloatCore` (rust-num/num#312, rust-lang/rust#42425)
- Fix overflow in `FloatCore::powi` exponent negation.
- Add doctests to all `FloatCore` methods.
37: Add Inv and Pow traits. r=cuviper a=clarcharr
This is not a breaking change, and closes#34 and #38.
This doesn't add any impls for the other `num` crates, just floats with `std` enabled. The trait has to be added before those other crates can be updated.
32: Implement CoreFloat trait r=cuviper a=vks
This is a subset of the `Float` trait, but works with `no_std`.
Some code was simplified by using `CoreFloat`.
30: Re-introduce the std feature r=vks a=cuviper
This is a port of @vks's rust-num/num#296, but without the feature-toggled changes to `Float`. Now `Float` and the newer `Real` are completely dependent on having `std` enabled. In the future we can consider adding separate more-limited float/real traits that can work without `std`, like the `BaseFloat` that was originally proposed in the former PR.
This is a breaking change with a bump to 0.2, since anyone currently using `default-features = false` will lose functionality. The actual API is otherwise unchanged, so my plan is to employ the "semver trick" -- publishing a new num-traits-0.1 that re-exports everything from 0.2 (with `std`). Thus all `num-traits` users should remain compatible even if they mix 0.1 and 0.2.
Closes#16.
We don't have implementations for many of the methods in `no_std`. It's
hostile to external implementors if some trait methods are conditional
on a feature, as that feature could be added by anyone in a dependency
tree. Instead, let's just live without these traits for now.
