Lucy Wayland - IEEE 754, FPUs and Other Animals
Most of us have used floats and doubles in our code, but very few people peer under the hood on how floating point numbers actually work. I will give a quick potted history of IEEE 754, a brief introduction to fixed point arithmetic, and then a reasonably comprehensive breakdown of how IEEE 754 floating point works.
Lucy is an applications engineer at ARM, but prior to that, most of her professional life has been writing and testing SW that flies planes and drives trains. She has a bit of a Cthulhu obsession.
