# isAdaptive

Determines the display style of the size representation.

```
var isAdaptive: Bool { get set }
```

## Discussion

The “adaptive” algorithm is platform specific and uses a different number of fraction digits based on the magnitude (in OS X v10.8: 0 fraction digits for bytes and KB; 1 fraction digits for MB; 2 for GB and above). Otherwise the result always tries to show at least three significant digits, introducing fraction digits as necessary.

Default is <doc://com.apple.documentation/documentation/Swift/true>.
