> Floating point is deterministic, what are you talking about?

Order of operations can change a result, for example. I suspect you mean that the algorithm never changes. While op means that mathematical operations which most folks would expect to be reliable are not.

They're not associative, sure. But that's a very far cry from claiming they're non-deterministic.

		There are enough problems for a 44 page paper titled "What Every Computer Scientist Should Know About Floating-Point Arithmetic"[1] I don't quibble on the language because I know what people mean. Most folks won't encounter most of the issues, generally. But expose your code to a large enough dataset, or be like me and write a CAD/CAM system with motion control and experience most of them. That's why I wrote hyperreal[2] 1: https://www.cs.tufts.edu/cs/40/docs/WhatEveryComputerScienti... 2: https://github.com/timschmidt/hyperreal
