Crate dtoa

  

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.

Example

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

Performance (lower is better)
