# vL128Rotate(_:_:)

128-bit left rotate.

## Declaration

```swift
func vL128Rotate(_ vA: vUInt32, _ vRotateFactor: vUInt8) -> vUInt32
```

## Parameters

- `vA`: The vector to shift.
- `vRotateFactor`: The number of bits to shift the vector.

## Return Value

Return Value Returns the shifted vector.

## Discussion

Discussion This function treats the entire 128-bit vector as a single value to rotate.
