Fast functions for printing floating-point primitives to a decimal string
APACHE-2.0 License
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.
