The combination of numerical methods and low-level hardware is fascinating. Those 20th century engineers were both smart and creative.

		Thank you! Amazing work! I've always had a soft spot for the 8087. Maybe implement the algorithm in C? Thank would be fun!

Love these deep dives. It’s fascinating to see how real, low-level engineering we all take for granted today unfolded. It’s incredible that the rough equivalent of an entire 160lb digital computer was built and baked into silicon.

Also incredible reverse engineering. In a time when seemingly all appreciation for expertise is gone it’s so refreshing to see.
