# NSSwapBigDoubleToHost(_:)

Swaps the bytes of a number.

```
func NSSwapBigDoubleToHost(_ x: NSSwappedDouble) -> Double
```

## Discussion

Converts the big-endian value in `x` to the current endian format and returns the resulting value. If it is necessary to swap the bytes of `x`, this function calls [`NSSwapDouble(_:)`](/documentation/Foundation/NSSwapDouble(_:)) to perform the swap.
