+   of this License, Derivative Works shall not include works that remain
+   separable from, or merely link (or bind by name) to the interfaces of,

+
+2. Grant of Copyright License. Subject to the terms and conditions of
+   this License, each Contributor hereby grants to You a perpetual,
+   worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+   copyright license to reproduce, prepare Derivative Works of,
+   publicly display, publicly perform, sublicense, and distribute the
+   Work and such Derivative Works in Source or Object form.
+
+3. Grant of Patent License. Subject to the terms and conditions of

+   (except as stated in this section) patent license to make, have made,
+   use, offer to sell, sell, import, and otherwise transfer the Work,
+   where such license applies only to those patent claims licensable
+   by such Contributor that are necessarily infringed by their
+   Contribution(s) alone or by combination of their Contribution(s)
+   with the Work to which such Contribution(s) was submitted. If You
+   institute patent litigation against any entity (including a
+   cross-claim or counterclaim in a lawsuit) alleging that the Work
+   or a Contribution incorporated within the Work constitutes direct
+   or contributory patent infringement, then any patent licenses
+   granted to You under this License for that Work shall terminate
+   as of the date such litigation is filed.
+
+4. Redistribution. You may reproduce and distribute copies of the
+   Work or Derivative Works thereof in any medium, with or without
+   modifications, and in Source or Object form, provided that You
+   meet the following conditions:
+
+   (a) You must give any other recipients of the Work or
+       Derivative Works a copy of this License; and
+
+   (b) You must cause any modified files to carry prominent notices
+       stating that You changed the files; and
+
+   (c) You must retain, in the Source form of any Derivative Works
+       that You distribute, all copyright, patent, trademark, and
+       attribution notices from the Source form of the Work,
+       excluding those notices that do not pertain to any part of
+       the Derivative Works; and
+
+   (d) If the Work includes a "NOTICE" text file as part of its
+       distribution, then any Derivative Works that You distribute must
+       include a readable copy of the attribution notices contained
+       within such NOTICE file, excluding those notices that do not
+       pertain to any part of the Derivative Works, in at least one
+       of the following places: within a NOTICE text file distributed
+       as part of the Derivative Works; within the Source form or
+       documentation, if provided along with the Derivative Works; or,
+       within a display generated by the Derivative Works, if and
+       wherever such third-party notices normally appear. The contents
+       of the NOTICE file are for informational purposes only and
+       do not modify the License. You may add Your own attribution
+       notices within Derivative Works that You distribute, alongside
+       or as an addendum to the NOTICE text from the Work, provided
+       that such additional attribution notices cannot be construed
+       as modifying the License.
+
+   You may add Your own copyright statement to Your modifications and
+   may provide additional or different license terms and conditions
+   for use, reproduction, or distribution of Your modifications, or
+   for any such Derivative Works as a whole, provided Your use,
+   reproduction, and distribution of the Work otherwise complies with
+   the conditions stated in this License.
+
+5. Submission of Contributions. Unless You explicitly state otherwise,
+   any Contribution intentionally submitted for inclusion in the Work
+   by You to the Licensor shall be under the terms and conditions of
+   this License, without any additional terms or conditions.
+   Notwithstanding the above, nothing herein shall supersede or modify
+   the terms of any separate license agreement you may have executed
+   with Licensor regarding such Contributions.
+
+6. Trademarks. This License does not grant permission to use the trade
+   names, trademarks, service marks, or product names of the Licensor,
+   except as required for reasonable and customary use in describing the
+   origin of the Work and reproducing the content of the NOTICE file.
+
+7. Disclaimer of Warranty. Unless required by applicable law or
+   agreed to in writing, Licensor provides the Work (and each
+   Contributor provides its Contributions) on an "AS IS" BASIS,
+   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+   implied, including, without limitation, any warranties or conditions

+   PARTICULAR PURPOSE. You are solely responsible for determining the
+   appropriateness of using or redistributing the Work and assume any
+   risks associated with Your exercise of permissions under this License.

+   negligent acts) or agreed to in writing, shall any Contributor be
+   liable to You for damages, including any direct, indirect, special,
+   incidental, or consequential damages of any character arising as a
+   result of this License or out of the use or inability to use the

+
+Pure Rust implementation of Ryū, an algorithm to quickly convert floating point
+numbers to decimal strings.
+
+The PLDI'18 paper [*Ryū: fast float-to-string conversion*][paper] by Ulf Adams
+includes a complete correctness proof of the algorithm. The paper is available
+under the creative commons CC-BY-SA license.
+
+This Rust implementation is a line-by-line port of Ulf Adams' implementation in
+C, [https://github.com/ulfjack/ryu][upstream].
+
+*Requirements: this crate supports any compiler version back to rustc 1.36; it
+uses nothing from the Rust standard library so is usable from no_std crates.*
+
+[paper]: https://dl.acm.org/citation.cfm?id=3192369
+[upstream]: https://github.com/ulfjack/ryu/tree/77e767f5e056bab96e895072fc21618ecff2f44b
+
+```toml
+[dependencies]
+ryu = "1.0"
+```
+
+<br>
+
+## Example
+
+```rust
+fn main() {
+    let mut buffer = ryu::Buffer::new();
+    let printed = buffer.format(1.234);
+    assert_eq!(printed, "1.234");
+}
+```
+
+<br>
+
+## Performance (lower is better)
+
+![performance](https://raw.githubusercontent.com/dtolnay/ryu/master/performance.png)
+
+You can run upstream's benchmarks with:
+
+```console
+$ git clone https://github.com/ulfjack/ryu c-ryu
+$ cd c-ryu
+$ bazel run -c opt //ryu/benchmark:ryu_benchmark
+```
+
+And the same benchmark against our implementation with:
+
+```console
+$ git clone https://github.com/dtolnay/ryu rust-ryu
+$ cd rust-ryu
+$ cargo run --example upstream_benchmark --release
+```
+
+These benchmarks measure the average time to print a 32-bit float and average
+time to print a 64-bit float, where the inputs are distributed as uniform random
+bit patterns 32 and 64 bits wide.
+
+The upstream C code, the unsafe direct Rust port, and the safe pretty Rust API
+all perform the same, taking around 21 nanoseconds to format a 32-bit float and
+31 nanoseconds to format a 64-bit float.
+
+There is also a Rust-specific benchmark comparing this implementation to the
+standard library which you can run with:
+
+```console
+$ cargo bench
+```
+
+The benchmark shows Ryū approximately 2-5x faster than the standard library
+across a range of f32 and f64 inputs. Measurements are in nanoseconds per
+iteration; smaller is better.
+
+## Formatting
+
+This library tends to produce more human-readable output than the standard
+library's to\_string, which never uses scientific notation. Here are two
+examples:
+
+- *ryu:* 1.23e40, *std:* 12300000000000000000000000000000000000000
+- *ryu:* 1.23e-40, *std:* 0.000000000000000000000000000000000000000123
+
+Both libraries print short decimals such as 0.0000123 without scientific
+notation.

+//!
+//! <br>
+//!
+//! Pure Rust implementation of Ryū, an algorithm to quickly convert floating
+//! point numbers to decimal strings.
+//!
+//! The PLDI'18 paper [*Ryū: fast float-to-string conversion*][paper] by Ulf
+//! Adams includes a complete correctness proof of the algorithm. The paper is
+//! available under the creative commons CC-BY-SA license.
+//!
+//! This Rust implementation is a line-by-line port of Ulf Adams' implementation
+//! in C, [https://github.com/ulfjack/ryu][upstream].
+//!
+//! [paper]: https://dl.acm.org/citation.cfm?id=3192369
+//! [upstream]: https://github.com/ulfjack/ryu
+//!
+//! # Example
+//!
+//! ```
+//! fn main() {
+//!     let mut buffer = ryu::Buffer::new();
+//!     let printed = buffer.format(1.234);
+//!     assert_eq!(printed, "1.234");
+//! }
+//! ```
+//!
+//! ## Performance (lower is better)
+//!
+//! ![performance](https://raw.githubusercontent.com/dtolnay/ryu/master/performance.png)
+//!
+//! You can run upstream's benchmarks with:
+//!
+//! ```console
+//! $ git clone https://github.com/ulfjack/ryu c-ryu
+//! $ cd c-ryu
+//! $ bazel run -c opt //ryu/benchmark
+//! ```
+//!
+//! And the same benchmark against our implementation with:
+//!
+//! ```console
+//! $ git clone https://github.com/dtolnay/ryu rust-ryu
+//! $ cd rust-ryu
+//! $ cargo run --example upstream_benchmark --release
+//! ```
+//!
+//! These benchmarks measure the average time to print a 32-bit float and average
+//! time to print a 64-bit float, where the inputs are distributed as uniform random
+//! bit patterns 32 and 64 bits wide.
+//!
+//! The upstream C code, the unsafe direct Rust port, and the safe pretty Rust API
+//! all perform the same, taking around 21 nanoseconds to format a 32-bit float and
+//! 31 nanoseconds to format a 64-bit float.
+//!
+//! There is also a Rust-specific benchmark comparing this implementation to the
+//! standard library which you can run with:
+//!
+//! ```console
+//! $ cargo bench
+//! ```
+//!
+//! The benchmark shows Ryū approximately 2-5x faster than the standard library
+//! across a range of f32 and f64 inputs. Measurements are in nanoseconds per
+//! iteration; smaller is better.
+//!
+//! ## Formatting
+//!
+//! This library tends to produce more human-readable output than the standard
+//! library's to\_string, which never uses scientific notation. Here are two
+//! examples:
+//!
+//! - *ryu:* 1.23e40, *std:* 12300000000000000000000000000000000000000
+//! - *ryu:* 1.23e-40, *std:* 0.000000000000000000000000000000000000000123
+//!
+//! Both libraries print short decimals such as 0.0000123 without scientific
+//! notation.
