# significandBitPattern

The raw encoding of the value’s significand field.

## Declaration

```swift
var significandBitPattern: Self.RawSignificand { get }
```

## Discussion

Discussion The significandBitPattern property does not include the leading integral bit of the significand, even for types like Float80 that store it explicitly.
