GitHub - dtolnay/zmij: Fast floating point to string conversion (original) (raw)
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 ofzmij::Buffer::new().format_finite(value) so a lower result indicates a faster library.
