This crate provides fast functions for printing floating-point primitives to an
io::Write. The implementation is a straightforward Rust port of Milo Yip's
C++ implementation dtoa.h. The original C++ code of each function is included
itoa for printing integer primitives.
Version requirement: rustc 1.0+
 = "0.4"
Performance (lower is better)
The function signature is:
dtoa::Floating is implemented for f32 and f64. The return value gives
the number of bytes written.
