The Many Faces of Number ⟷ String Conversions – Dvir Yitzchaki - C++ on Sea 2022
Slides: https://github.com/philsquared/cppons...

Seemingly a basic task, converting between numbers and their string representation is a problem which has kept C++ busy since its birth.
C++ inherited several library functions from C dealing with such conversions and has kept adding more on almost every new standard, the latest examples being to/from_chars from C++17 and C++20’s format library. This didn’t stop non-standard libraries, like Boost, from offering even more ways to do those conversions.
In this talk we will explore,

std::atoi
std::stoi
std::to_string
std::from_chars
boost::lexical_cast
std::scan
and more. We will try to understand why the number-string conversion problem is being solved repeatedly, compare the API, implementation and performance of these utilities, and see that, even now, there is still room for improvement.
