# CFNumberFormatterCreate(_:_:_:)

Creates a new CFNumberFormatter object, localized to the given locale, which will format numbers to the given style.

```
func CFNumberFormatterCreate(_ allocator: CFAllocator!, _ locale: CFLocale!, _ style: CFNumberFormatterStyle) -> CFNumberFormatter!
```

## Parameters

`allocator`

The allocator to use to allocate memory for the new object. Pass `NULL` or [`kCFAllocatorDefault`](/documentation/CoreFoundation/kCFAllocatorDefault) to use the current default allocator.

`locale`

A locale to use for localization. If `NULL`, the function uses the default system locale. Use [`CFLocaleCopyCurrent()`](/documentation/CoreFoundation/CFLocaleCopyCurrent()) to specify the locale of the current user.

`style`

A number style. See [Number Formatter Styles](/documentation/CoreFoundation/number-formatter-styles) for possible values.

## Return Value

A new number formatter, localized to the given locale, which will format numbers using the given style. Returns `NULL` if there was a problem creating the formatter. Ownership follows the [The Create Rule](https://developer.apple.com/library/archive/documentation/CoreFoundation/Conceptual/CFMemoryMgmt/Concepts/Ownership.html#//apple_ref/doc/uid/20001148-103029).
