I got hung up on this line:

This requires deterministic math with explicit rounding modes and precision, not the platform-dependent behavior you get with floats.

Aren't floats mostly standardized these days? The article even mentions that standard. Has anyone here seen platform-dependent float behaviour?

Not that this affects the article's main point, which is perfectly reasonable.

The IEEE standard actually does not dictate a rounding policy
