## Relation With Other Work
## Users and Related Work
The fast_float library is part of:
- GCC (as of version 12): the `from_chars` function in GCC relies on fast_float.
- [WebKit](https://github.com/WebKit/WebKit), the engine behind Safari (Apple's web browser)
- [DuckDB](https://duckdb.org)
- [Apache Arrow](https://github.com/apache/arrow/pull/8494) where it multiplied the number parsing speed by two or three times
- [Google Jsonnet](https://github.com/google/jsonnet)
- [ClickHouse](https://github.com/ClickHouse/ClickHouse)
The fastfloat algorithm is part of the [LLVM standard libraries](https://github.com/llvm/llvm-project/commit/87c016078ad72c46505461e4ff8bfa04819fe7ba).
There is a [derived implementation part of AdaCore](https://github.com/AdaCore/VSS).

The fast_float library provides a performance similar to that of the [fast_double_parser](https://github.com/lemire/fast_double_parser) library but using an updated algorithm reworked from the ground up, and while offering an API more in line with the expectations of C++ programmers. The fast_double_parser library is part of the [Microsoft LightGBM machine-learning framework](https://github.com/microsoft/LightGBM).
