Żmij ECMA is a fork of the [Żmij][zmij-crate] crate adjusted to comply with the ECMAScript [number-to-string][number-to-string] algorithm.

[number-to-string]: https://tc39.es/ecma262/#sec-numeric-types-number-tostring
---
Pure Rust implementation of Żmij, an algorithm to quickly convert floating point
numbers to decimal strings.
This Rust implementation is a line-by-line port of Victor Zverovich's
implementation in C++, [https://github.com/vitaut/zmij][upstream].
[upstream]: https://github.com/vitaut/zmij/tree/d8cb94516d0c480d6d70851ca677beae6ba721fc
## Example
```rust
fn main() {
let mut buffer = zmij_ecma::Buffer::new();
let printed = buffer.format(1.234);
assert_eq!(printed, "1.234");
}
```
## Performance
The [dtoa-benchmark] compares this library and other Rust floating point
formatting implementations across a range of precisions. The vertical axis in
this chart shows nanoseconds taken by a single execution of
`zmij_ecma::Buffer::new().format_finite(value)` so a lower result indicates a faster
library.
