# `libm`
A Rust implementations of the C math library.
## Usage
`libm` provides fallback implementations for Rust's [float math functions] in
`core`, and the [`core_float_math`] feature. If what is available suits your
needs, there is no need to add `libm` as a dependency.
If more functionality is needed, this crate can also be used directly:
```toml
[dependencies]
libm = "0.2.11"
```
