To Int or to Uint, This is the Question - Alex Dathskovsky - CppCon 2024
---
In our daily work, we often use integral data types to perform arithmetic calculations, but we may not always consider how the selection of the data type can affect performance and compiler optimizations. This talk will delve into the importance of choosing the correct data type for the job and how it impacts compiler optimizations. We will also examine the overall performance implications for the application. We will explore specific algorithms where using unsigned data types is more beneficial and other situations where signed data types are the best choice. Furthermore this talk will dive into the differences between signed and unsigned integers, how the processor handles certain operations and explain many of the surprising pitfalls of using integral types.
Attendees will come away with a deeper understanding of how data type selection can impact their code and how to make better choices for optimal performance.
This session will follow the guidelines from my short article on LinkedIn but it will go into higher details and contain more examples and explanations.

CppCon is the annual, week-long face-to-face gathering for the entire C++ community. The conference is organized by the C++ community for the community. You will enjoy inspirational talks and a friendly atmosphere designed to help attendees learn from each other, meet interesting people, and generally have a stimulating experience. Taking place this year in Aurora, Colorado, near the Denver airport, and including multiple diverse tracks, the conference will appeal to anyone from C++ novices to experts.
