Stephan T. Lavavej “Floating-Point ＜charconv＞: Making Your Code 10x Faster With C++17's Final Boss”

I'm glad you liked my charconv talk! Here's a complete list of my recorded conference talks: BoostCon/C++Now 2012: Regex In C++11 And Boost: link GoingNative 2012: STL11: Magic && Secrets: link GoingNative 2013: Don't Help The Compiler: link GoingNative 2013: rand() Considered Harmful: link CppCon 2014: STL Features And Implementation Techniques: link CppCon 2015: functional: What's New, And Proper Usage: link CppCon 2016: tuple: What's New, And How It Works: link CppCon 2018: Class Template Argument Deduction for Everyone: link CppCon 2019: Floating-Point charconv: Making Your Code 10x Faster With C++17's Final Boss: ▶ this video CppCon 2020: C++20 STL Features: 1 Year of Development on GitHub: link Pure Virtual C++ 2022: MSVC C++20/23 Update: link

I really love this talk in particular: ▶ this video (On charconv) But any of the ones I've seen from Stephan have been fantastic, I think, although I'm not actually sure if I've seen more. He seems to have a lot of talks on very specific subjects, which can be really fun. > Hyrum Wright is in the audience yelling interjections as a result of Hyrum's law This sounds absolutely hilarious, I'll have to take a look.

Stephan T Lavavej also had a surprisingly fun and approachable talk on that problem, talking about how charconv got implemented and improved in Microsoft's C++ standard library: ▶ this video

Actually, there's even more recent research into doing this really efficiently, using an algorithm called Ryū. [e] link [-4] link [1.73] ▶ this video

For those interested in more information about performance was achieved, Stephan Lavavej gave a talk about this very subject during CppCon 2019 [1]. [1] ▶ this video
