# format(_:)

Formats an decimal, using this style.

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

## Parameters

`value`

The decimal 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 decimal. To format a single integer, use the 1414588 instance method [`formatted(_:)`](/documentation/Foundation/Decimal/formatted(_:)), passing in an instance of [`Decimal.FormatStyle.Percent`](/documentation/Foundation/Decimal/FormatStyle/Percent), or call [`formatted()`](/documentation/Foundation/Decimal/formatted()) to use a default style.
