# maximumFractionDigits

The maximum number of digits after the decimal separator.

## Declaration

```swift
var maximumFractionDigits: Int { get set }
```

## Discussion

Discussion By default, this property is set to 0. The following code demonstrates the effect of setting maximumFractionDigits when formatting a number: var numberFormatter = NumberFormatter()

numberFormatter.maximumFractionDigits = 0 // default numberFormatter.string(from: 123.456) // 123

numberFormatter.maximumFractionDigits = 3 numberFormatter.string(from: 123.456789) // 123.457
