<p>A double-to-string conversion algorithm based on <a href="https://fmt.dev/papers/Schubfach4.pdf">Schubfach</a> and <a href="https://github.com/ibireme/c_numconv_benchmark/blob/master/vendor/yy_double/yy_double.c">yy</a>.</p>

<p>This Rust implementation is a line-by-line port of Victor Zverovich’s

implementation in C++, <a href="https://github.com/vitaut/zmij">https://github.com/vitaut/zmij</a>.</p>

<p>The <a href="https://github.com/dtolnay/dtoa-benchmark">dtoa-benchmark</a> 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
|
||
<code>zmij::Buffer::new().format_finite(value)</code> so a lower result indicates a
|
||
faster library.</p>
