Implementing 2D graphics operations with fixed point arithmetic isn't hard, and has the benefit of being absolutely exactly reproducible on 1980s hardware (hence why TeX uses it). You can do very sophisticated work entirely with fixed point (such as the first Playstation), and I suspect we're going to see more noise from the ML people about using it for silicon space efficiency reasons.
