About this package

A double-to-string conversion algorithm based on Schubfach and yy

Żmij

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.

Example

fn main() {
    let mut buffer = zmij::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::Buffer::new().format_finite(value) so a lower result indicates a faster library.
