# Vector4.DistanceBetweenSquared

```csharp
static float DistanceBetweenSquared(in Vector4 a, in Vector4 b)
```

Returns squared distance between the 2 given vectors. This is faster than [DistanceBetween](/api/Vector4/DistanceBetween),
and can be used for things like comparing distances, as long as only squared values are used.

### Parameters

- `in a` (`Vector4`)
- `in b` (`Vector4`)

### Returns

`float`

Declared in [Vector4](/api/Vector4).
Assembly: `Sandbox.System`.
