Crlibm

======

This crate is a binding to [CRlibm][], an efficient and proved

correctly-rounded mathematical library.

For the user convenience, this module embeds the relevant C code from

the [CRlibm Git repository][crlibm-git].

Note that the C code of CRlibm is mature but superseded by

[MetaLibm][] ([repository][MetaLibm-git]) and will therefore not

receive updates.

## Example

```rust

use crlibm::*;

let x = sinpi_rd(2.);

let y = sinpi_rn(2.);

let z = sinpi_ru(2.);

```

## Features

Be default, the crate uses portable implementations of the logarithm.

The feature `log_double_extended` enables implementations optimized

for processors with double-extended hardware (if in addition the

correct platform is detected).  These versions may not be faster.
