I'm not quite sure how much you mean by "a lot" – it seems to be one
repo [1], but more importantly, you could try to disable the tests that
require external fetches.

I'd call this a "Floating point number parser" or if you prefer the
verb form "Parse floating point numbers".

"@code{fast_float} is a header-only C++ library for parsing floating
point numbers from strings." If you want to mention its speed, add
"Benchmarks show that it is several times faster than strtod."

Weird choice, but okay.
