|
|
Numeric traits for generic mathematics in Rust.
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
Add this to your `Cargo.toml`:
|
||
|
|
|
||
|
|
```toml
|
||
|
|
[dependencies]
|
||
|
|
num-traits = "0.2"
|
||
|
|
```
|
||
|
|
|
||
|
|
## Features
|
||
|
|
|
||
|
|
This crate can be used without the standard library (`#![no_std]`) by disabling
|
||
|
|
the default `std` feature. Use this in `Cargo.toml`:
|
||
|
|
|
||
|
|
```toml
|
||
|
|
[dependencies.num-traits]
|
||
|
|
version = "0.2"
|
||
|
|
default-features = false
|
||
|
|
# features = ["libm"] # <--- Uncomment if you wish to use `Float` and `Real` without `std`
|
||
|
|
```
|
||
|
|
|
||
|
|
The `Float` and `Real` traits are only available when either `std` or `libm` is enabled.
|
||
|
|
|
||
|
|
The `FloatCore` trait is always available. `MulAdd` and `MulAddAssign` for `f32`
|
||
|
|
and `f64` also require `std` or `libm`, as do implementations of signed and floating-
|
||
|
|
point exponents in `Pow`.
|
||
|
|
|
||
|
|
