This crate provides fast conversion of floating point primitives to decimal
strings. The implementation is a straightforward Rust port of [Milo Yip]'s C++
implementation [dtoa.h]. The original C++ code of each function is included in
comments.
See also [`itoa`] for printing integer primitives.
*Version requirement: rustc 1.36+*

[dtoa.h]: https://github.com/miloyip/rapidjson/blob/master/include/rapidjson/internal/dtoa.h

```
## Example
```rust
fn main() {
let mut buffer = dtoa::Buffer::new();
let printed = buffer.format(2.71828f64);
assert_eq!(printed, "2.71828");
}
```
