# format(_:)

Formats a floating-point value, using this style.

```
func format(_ value: Value) -> String
```

## Parameters

`value`

The floating-point value to format.

## Return Value

A string representation of `value`, formatted according to the style’s configuration.

## Discussion

Use this method when you want to create a single style instance, and then use it to format multiple floating-point values. To format a single value, use the <doc://com.apple.documentation/documentation/Swift/BinaryFloatingPoint> instance method <doc://com.apple.documentation/documentation/Swift/BinaryFloatingPoint/formatted(_:)-83x4n>, passing in an instance of [`FloatingPointFormatStyle.Currency`](/documentation/Foundation/FloatingPointFormatStyle/Currency).
