## Declaration

```swift
init(sign: FloatingPointSign, exponentBitPattern: UInt, significandBitPattern: UInt16)
```

## Parameters

- `sign`: The sign of the new value.
- `exponentBitPattern`: The bit pattern to use for the exponent field of the new value.
- `significandBitPattern`: The bit pattern to use for the significand field of the new value.
