# locale

The locale to use when scanning.

## Declaration

```swift
var locale: Any? { get set }
```

## Discussion

Discussion A scanner’s locale affects the way it interprets numeric values from the string. In particular, a scanner uses the locale’s decimal separator to distinguish the integer and fractional parts of floating-point representations. A scanner with no locale set uses non-localized values. New scanners have no locale by default.
