New video out today! This one is an introduction to the fascinating technique called Double Double arithmetic.

This video originally had another intro with a coding example showing the amazing precision of double doubles. But I cut it after I accidentally lost half the audio. If I can edit something watchable, I will upload the original intro as a Patreon exclusive. Also I have an e-book coming for this series shortly. Although, I have to reno a house at the moment, so not sure when these items will be ready.

Thank you for the support all, it is much appreciated :)

Double it Like Dekker (Part 1): A Remarkable Technique to Double Floating Point Precision

This video is an introduction to Double Double arithmetic. Which is a technique used to greatly improve the precision of floating point computations in programming. It was first proposed by T. J. (Dirk) Dekker in his paper from 1971.
