I have two proposals:
If we have the cases where the lower bound of a range might be inexact (or
perhaps absent) and the upper bound is exact—or vice versa—we could define the
following:
```
enum Estimation {
Exact(T),
Inexact(T),
Absent,
}
enum Precision {
Estimation,
// min - max
Range(Estimation, Estimation)
}
```
2) If we don't need to consider the exactness of bounds and a simple
interval suffices, this alternative could be used:
```
enum Precision {
Exact(T),
Inexact(T),
Absent,
Between(Interval)
}
```
