@tabatkins So I guess `round(strategy, ±∞, ±∞)` should also depend on `strategy`?
- `round(up, +∞, ±∞) = ∞`
- `round(up, −∞, ±∞) = NaN` since the limit in not unique, e.g.
```
lim_{x→−∞} round(up, x, 2x) = −0
lim_{x→−∞} round(up, x, x) = −∞
```
- `round(down, −∞, ±∞) = −∞`
- `round(down, +∞, ±∞) = NaN` since the limit in not unique, e.g.
```
lim_{x→+∞} round(down, x, 2x) = +0
lim_{x→+∞} round(down, x, x) = +∞
```
- `round(to-zero, ±∞, ±∞) = NaN` since the limit in not unique, e.g.
```
lim_{x→±∞} round(to-zero, x, 2x) = ±0
lim_{x→±∞} round(to-zero, x, x) = ±∞
```
- `round(nearest, ±∞, ±∞) = NaN` since the limit in not unique, e.g.
```
lim_{x→±∞} round(nearest, x, 3x) = ±0
lim_{x→±∞} round(nearest, x, x) = ±∞
```
