Alright, future engineers!
**Round-off Error:** Error from storing exact numbers with limited precision in computers.
Ex: 1/3 stored as 0.33333.
Pro-Tip: Use double precision & re-order ops to minimize accumulation in long calculations!

“In 1980, #Intel released the #Intel8087 #FloatingPoint coprocessor, a chip that could make math up to 100 times faster. As well as arithmetic and square roots, the 8087 computed #transcendental functions including #tangent, #exponentiation, and #logarithms.
But it all depended on a 69-bit adder: "The arithmetic heart of the floating-point execution unit is centered about a #nanomachine comprised of the adder and its related #registers, #shifters and control circuitry," as the patent describes it”

🚀✨ 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. 💻🧠
