Implementing epsilon function to retrieve EPSILON constant

Hey!

This PR exposes a new `epsilon` function in the `Float` trait so that users can access the `EPSILON` constant on the float types. I figured as this was such a minimal change it was easier to get a PR in offering the change then write up an issue.

For me this is a valuable addition. When writing linear algebra or other optimization routines with generic floats we often want to check if some stopping criteria is reached, often something like: `(a - b).abs() < eps`. Having access to a standard _small value_ would make this a little easier.

Homu 4fb22849b4 Auto merge of #222 - SuperFluffy:serde_0.8, r=cuviper
Use serde 0.8

I updated `bigint`, `complex`, and `rational` to use `serde 0.8`, and also fixed deserialization and the `serde` feature as such in the `rational` crate (didn't add any tests, but it compiles now).

Similar to https://github.com/rust-num/num/pull/196 for `num/complex`, “`use serde;`” needed to be removed in `num/rational`.

Fix import serde and rational deserialization

Similar to #196 for num/complex, “use serde;” needed to be removed in num/rational.

Also, deserialization of `num/rational` needed to be fixed by adding type annotations.

This is in response to https://github.com/rust-num/num/pull/222#issuecomment-239957062 of issue https://github.com/rust-num/num/pull/222.

Also added a travis line, in response to https://github.com/rust-num/num/pull/222#issuecomment-239957062. Hope it works.

Add a trait for floating-point constants

The pull request is to address issue #194. In order to keep the library organized, I’ve introduced a new trait for the new functionality. The trait is supposed to closely follows the [`consts`](https://doc.rust-lang.org/std/f64/consts/index.html) module from the standard library. There are at least the following three open questions:

1. What should the name of the trait be? Currently, it’s `Constant`; an alternative is `Consts`.
2. What should the names of the getters be? Currently, they are lower-case versions of the constants defined in the `consts` module. Note that `Float` provides `log2` and `log10`, whereas `LOG_2` and `LOG_10` get translated into `log_2` and `log_10`, respectively.
3. Should `Float` require the new trait? Or should it be left up to the user?

Please let me know what you think. Thank you!

Regards,
Ivan

Homu 10a57ef1a6 Auto merge of #219 - cuviper:tiny-inline, r=hauleth
Inline small functions, especially wrappers

We already had `#[inline]` throughout a lot of the code, but notably some
functions which simply wrap inherent methods were not inlined.  That means
external references will get a full function call, when they could have been
optimized to as little as one opcode.

This PR inlines all functions that look tiny enough for this to matter.

Fixes #218.

traits: add `to_degrees` and `to_radians` on `Float`

To avoid a breaking change, these have crude default implementations as
well as better implementations for `f32` and `f64` in particular.  They
don't use the inherent methods though, because `f32` didn't stabilize
those until Rust 1.7.
