# maximumIntegerDigits

The maximum number of digits before the decimal separator.

## Declaration

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

## Discussion

Discussion By default, this property is set to 42. The following code demonstrates the effect of setting maximumIntegerDigits when formatting a number: var numberFormatter = NumberFormatter()

numberFormatter.maximumIntegerDigits = 42 // default numberFormatter.string(from: 12345) // 12345

numberFormatter.maximumIntegerDigits = 3 numberFormatter.string(from: 12345) // 345
