# CFNumberFormatterGetDecimalInfoForCurrencyCode(_:_:_:)

Returns the number of fraction digits that should be displayed, and the rounding increment, for a given currency.

## Declaration

```swift
func CFNumberFormatterGetDecimalInfoForCurrencyCode(_ currencyCode: CFString!, _ defaultFractionDigits: UnsafeMutablePointer<Int32>!, _ roundingIncrement: UnsafeMutablePointer<Double>!) -> Bool
```

## Parameters

- `currencyCode`: A string containing a ISO 4217 3-letter currency code. For example, AUD for Australian Dollars, EUR for Euros.
- `defaultFractionDigits`: Upon return, contains the number of fraction digits that should be displayed for the currency specified by currencyCode.
- `roundingIncrement`: Upon return, contains the rounding increment for the currency specified by currencyCode, or 0.0 if no rounding is done by the currency.

## Return Value

Return Value true if the information was obtained successfully, otherwise false (for example, if the currency code is unknown or the information is not available).

## Discussion

Discussion The returned values are not localized because these are properties of the currency.
