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.
Version requirement: rustc 1.36+
