Formatting Floating-Point Numbers

By Victor Zverovich

In this talk you will learn more than you ever wanted to know about floating-point formatting, from basics to recent developments in the area. You will find out why printf drags in a multiprecision arithmetic library, what the C++17 std::to_chars all about, why it is so difficult to implement, and how to do it efficiently. You will also learn how the popular {fmt} library and the forthcoming C++20 std::format do floating-point formatting, and how it can benefit your code.

By the end of the talk you will be able to convert binary floating-point to decimal in your mind or you will get your money back!
