🚀✨ Behold, the thrilling tale of querying 3 billion vectors—a journey where Vicki Boykis heroically attempts to decode Jeff Dean's cryptic wisdom on #mapreduce. Spoiler: It's basically a nerdy treasure hunt for semantically similar items, but with more floating-point numbers than your brain can handle. 💻🧠

0.1 + 0.2 In SQL = 0.30000000000000004?!

SQL floating point precision is broken! Adding 0.1 + 0.2 creates a number with precision errors. This breaks financial calculations! Watch!

Floating-Point Error Handling in C++: What Actually Works - Johnny's Software Lab

Floating-point errors are unavoidable, but how you detect and handle them can make the difference between clean, high-performance C++ code and a debugging nightmare. In this article, we explore the practical techniques for handling NaNs, infinities, and other FP errors — from manual checks to sticky bits and hardware traps — and reveal which approaches actually work without sabotaging performance.
