## Usage
|
|
|
|
|
|
|
|
Add this to your `Cargo.toml`:
|
|
|
|
|
|
|
|
```toml
|
2014-11-20 20:07:56 +00:00
|
|
|
[dependencies]
|
2018-02-01 00:19:00 +00:00
|
|
|
num-traits = "0.2"
|
2014-09-23 20:27:05 +00:00
|
|
|
```
|
|
|
|
|
|
|
|
and this to your crate root:
|
|
|
|
|
|
|
|
```rust
|
2017-12-19 01:35:41 +00:00
|
|
|
extern crate num_traits;
|
2014-09-23 20:27:05 +00:00
|
|
|
```

|
## Features
|
|
|
|
|
|
|
|
This crate can be used without the standard library (`#![no_std]`) by disabling
|
2018-04-10 08:42:35 +00:00
|
|
|
the default `std` feature. Use this in `Cargo.toml`:
|
2018-02-01 00:16:41 +00:00
|
|
|
|
|
|
|
```toml
|
|
|
|
[dependencies.num-traits]
|
2018-02-01 00:19:00 +00:00
|
|
|
version = "0.2"
|
2018-02-01 00:16:41 +00:00
|
|
|
default-features = false
|
|
|
|
```
|
|
|
|
|
2018-02-07 11:47:12 +00:00
|
|
|
The `Float` and `Real` traits are only available when `std` is enabled. The
|
2018-05-09 00:35:59 +00:00
|
|
|
`FloatCore` trait is always available. `MulAdd` and `MulAddAssign` for `f32`
|
|
|
|
and `f64` also require `std`, as do implementations of signed and floating-
|
|
|
|
point exponents in `Pow`.
|
2018-02-01 00:16:41 +00:00
|
|
|
|
2018-05-11 22:50:48 +00:00
|
|
|
Implementations for `i128` and `u128` are only available with Rust 1.26 and
|
|
|
|
later. The build script automatically detects this, but you can make it
|
|
|
|
mandatory by enabling the `i128` crate feature.
