The fast_float library provides fast header-only implementations for the C++ from_chars
functions for `float` and `double` types. These functions convert ASCII strings representing
decimal values (e.g., `1.3e10`) into binary types. We provide exact rounding (including
round to even). In our experience, these `fast_float` functions are faster than any other comparable number-parsing functions. They provide a performance similar to that of the [fast_double_parser](https://github.com/lemire/fast_double_parser) but using an novel algorithm reworked from the ground up, and while offering an API more in line with the expectations of C++ programmers.

Specifically, `fast_float` provides the following two functions with a C++17-like syntax (the library itself only requires C++11):

## Relation With Other Work
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 novel algorithm reworked from the ground up, and while offering an API more in line with the expectations of C++ programmers.
## Users
This library is used by [Apache Arrow](https://github.com/apache/arrow/pull/8494) where it multiplied the number parsing speed by two or three times.
