# String.LocalizationValue.Placeholder.float

The single-precision floating-point type, as used for replacement values with the localized string placeholder syntax.

## Declaration

```swift
case float
```

## Discussion

Discussion To insert a float into a placeholder, use the syntax \(placeholder: .float). The various String(localized:) initializers apply a locale-appropriate FormatStyle to the numeric value, based on the locale: parameter or the LocalizedStringResource.
