fastfloat
Fast and exact implementation of the C++ from_chars functions for number types: 4x to 10x faster than strtod, part of GCC 12 and WebKit/Safari
This function could be simplified a bit: https://github.com/lemire/fast_float/blob/7eae925b51fd0f570ccd5c880c12e3e27a23b86f/include/fast_float/ascii_number.h#L27 replace its implementation with: `return ((val & 0xF0F0F0F0F0F0F0F0u) & (val + 0x0606060606060606u)) == 0x3030303030303030u;`
This is useful for projects that integrate FastFloat via `add_subdirectory`. In many cases the vendored FastFloat is not part of the public API and should not be exposed as such.

Are there any plans to add support for hexadecimal strings? While not as common as the decimal representation, I have a few use cases related to parsing languages which have...
I'm writing a library for some scientific data management, and I have a need to parse strings of the sort `"+12.345e-02(13)"`**, which contains the value `0.12345` and the error `0.00013`....
The following blog post could be useful if we ever want to parsing `uint8_t` values: https://lemire.me/blog/2023/11/28/parsing-8-bit-integers-quickly/
As a follow up to #216 . It's not branchless, but, nevertheless, allow to extract part of the logic so it can be reused. Running the benchmark shows no difference...
`18446744073709551615e-65` rounds to `0`, and it is the largest possible value with exponent `-65`. Therefore, we can assume the minimal exponent for which we don't round to zero actually is...
The library is already correct on these cases, but we should be explicit. Contributed by @deadalnix ``` 1/ Where float stop rounding to 0. 0.7006492321624085354e-45 0.7006492321624085355e-45 2/ Where float start...
