# Vector3.DistanceBetweenSquared

```csharp
static float DistanceBetweenSquared(in Vector3 a, in Vector3 b)
```

Returns squared distance between the 2 given vectors. This is faster than [DistanceBetween](/api/Vector3/DistanceBetween),
and can be used for things like comparing distances, as long as only squared values are used.

### Parameters

- `in a` (`Vector3`)
- `in b` (`Vector3`)

### Returns

`float`

Declared in [Vector3](/api/Vector3).
Assembly: `Sandbox.System`.
