If you care exclusively about numerical stability and performance, why _this_ set of operators (e.g., there’re plenty of good reasons to include expm1 or log1p and certainly trigonometric functions)? It’d be an interesting research problem to measure and identify the minimal subset of operators (and I suspect it’d look differently than what you’d expect from an FPU).
If you care exclusively about minimalism, why not limit yourself to the Meijer-G function (or some other general-purpose alternative)?
