Vinzent Steinberg efad5329b4 Rename CoreFloat to FloatCore 2018-02-07 12:34:14 +01:00
Vinzent Steinberg 8a7f383eb1 Implement CoreFloat trait
This is a subset of the `Float` trait, but works with `no_std`.
Some code was simplified by using `CoreFloat`.

Josh Stone e6bb97b3ac Make `Float` and `Real` depend on the `std` feature
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.

Vinzent Steinberg a843027b56 Re-introduce the std feature
This is a port of @vks's rust-num/num#296, but without the feature-
toggled changes to `Float`.

bors[bot] 93be5dbff2 Merge #23
23: Add RealNum trait for real data types (Float, but without floating-point specific features) r=cuviper a=yoanlcq

This is supposed to fix [#19](https://github.com/rust-num/num-traits/issues/19); I assumed going ahead would be better than bumping the thread.  

In any case, I understand that it is a quite significant addition and won't mind too much if it doesn't make it.

This adds a new `RealNum` trait, along with a universal impl `impl<T: Float> RealNum for T { ... }`.  
Therefore, this shouldn't be a breaking change, except in places where both traits are imported (which obviously only happened in a few places in this crate).

The intent is that generic code may prefer to use `RealNum` instead of `Float` when floating-point isn't a requirement. In the future (next major version ?), I guess `Float` could be made to only provide floating-point-specific features on top of `RealNum`.

Most of the code+doc was copy-pasted from `Float`, but the doc comments should be up-to-date with the situation; `Float` only makes an appearance when talking about NaN and infinity.

Issues I've seen : 
- `RealNum` might not be the name we want;
- I've mentioned that `sqrt()` is allowed to panic if the input is negative and has no meaningful NaN representation;
- Should we do that too for e.g `log()` ? Like `sqrt()`, it's supposed to return Nan when `x < 0`.

Thanks for your time. :)

Josh Stone 42a610d323 Move num-traits to its own repo
All the prior `num` history is kept, so old `num-traits` tags are still
valid, but future development here will be just for `num-traits`.

The doc root URLs are correct as they are, the URL does not include the
crate name itself.

Josh Stone 865c491ce2 num: remove `pub` from sub-crates
Rust 1.4 through 1.7 will issue warnings that `pub extern crate` does
not work as expected, although it appears to be fine.  But Rust 1.8 and
later issue `#[warn(private_in_public)]` for `pub use num_foo as foo` if
that crate isn't public, and that's headed toward a hard error.

@bluss suggested instead `pub mod foo { pub use num_foo::*; }`, which
I thought I had tried before, but it appears to work fine on all
versions of Rust.  Let's do it!

A small downside is that docs for `num::foo` now just show the wildcard
reexport, instead of direct documentation, but at least there's a link
to follow to the sub-crate.

It's a breaking change that `num::num_foo` paths are no longer public,
but we didn't really want those exposed in the first place.  I consider
this minor -- people should either use the `num::foo` module as before
the split-up, or use the `num_foo` crate directly.

Fixes #189.

Erick Tryzelaar 112923eec5 Add support for Serde 0.7.
Serde 0.7 dropped it's dependency on num, so this patch moves
the implementations here. For the sake of a better implementation,
this just serializes BigUint as a `Vec<u32>`, `BigInt` as a
`(u8, Vec<u32>)`, `Complex<T>` as a `(T, T)`, and `Ratio<T>`
as a `(T, T)`.

Brian Smith 9e3e8552ac Make `rand` and `rustc-serialize` dependencies optional.
Previously, the `rand` and `rustc-serialize` dependencies were optional
except they were required for the `bigint` feature.

Make the dependency on the `rand` crate optional in all cases.
including when the `bigint` feature is selected. Some of the tests for
the bigint feature are randomized so, while `rand` is now an optional
dependency, it is a non-optional dev-dependency.

Similarly, make the dependency on the `rustc-serialize` crate optional
in all cases, including when the `bigint` feature is selected.

Josh Stone 22722ac55d pow: shift exp powers of 2 before accumulating
We can save a multiplication if we start the accumulation basically at
the first set bit of the exponent, rather than starting at one and
waiting to multiply.  We only need one itself if the exponent is zero,
which is easy to pre-check.

Before:
    test pow_bench         ... bench:   8,267,370 ns/iter (+/- 93,319)

After:
    test pow_bench         ... bench:   7,506,463 ns/iter (+/- 116,311)

Josh Stone 2e3e575117 Fix the feature masks in the approx_sqrt doc example
The hidden "mod test" layout of the first example has been broken for a
while, but it wasn't noticed because rustdoc wasn't passing any features
at all.  That was fixed in rust-lang/rust#30372, and now we need to get
our ducks in a row too.

root 4c123a9e71 Make rustc-serialize, bignum, rational, complex into opt-out features
Making bignum optional allows skipping the rustc-serialize and rand
dependencies too, and it makes a big difference in num's build time.

With default (all) features, clean build time including dependencies: 27
seconds.

With no default features, clean build time including dependencies (none):
5 seconds.

Moving to stable required vendoring a couple of minor things (notably,
radix formatting).

Josh Stone 043a5b2918 pow: avoid unnecessary overflows
The code was performing an extra squaring of the base, which might
trigger an arithmetic overflow that doesn't matter to the result.  Now
this squaring is only attempted when enough exp remains to need it.

A new doctest tries pow(6u8, 3), where an extra square would exceed 256.
