Scala seems to take the sign into account during sorting and Rust does not.
Perhaps we just need to document this as an edge case in the compatibility
guide.
## Scala
```scala
val x: Seq[Float] = Seq(0.0f, -0.0f, 0.0f, -0.0f, 1.0f, -1.0f)
println(x.sorted)
```
Output: `List(-1.0, -0.0, -0.0, 0.0, 0.0, 1.0)`
## Rust
```rust
let mut v = vec![0.0_f32, -0.0_f32, 0.0_f32, -0.0_f32, 1.0_f32, -1.0_f32];
v.sort_by(|a, b| a.partial_cmp(b).unwrap_or(std::cmp::Ordering::Greater));
println!("{:?}", v);
```
Output: `[-1.0, 0.0, -0.0, 0.0, -0.0, 1.0]`
