# init(style:allowedUnits:spellsOutZero:includesActualByteCount:locale:)

Initializes a byte count format style.

## Declaration

```swift
init(style: ByteCountFormatStyle.Style = .file, allowedUnits: ByteCountFormatStyle.Units = .all, spellsOutZero: Bool = true, includesActualByteCount: Bool = false, locale: Locale = .autoupdatingCurrent)
```

## Parameters

- `style`: The style of byte count to express, such as memory or file system storage.
- `allowedUnits`: The units the format style can use to express the byte count.
- `spellsOutZero`: A Boolean value that indicates whether the format style should spell out zero-byte values as text, like Zero kB.
- `includesActualByteCount`: A Boolean value that indicates whether the format style should include the exact byte count, in addition to expressing it in terms of units. For example, 1 kB (1,024 bytes).
- `locale`: The locale to use to format the numeric part of the byte count.

## Discussion

Discussion In situations that can infer the ByteCountFormatStyle type, you can call byteCount(style:allowedUnits:spellsOutZero:includesActualByteCount:) instead of explicitly using this initializer. This is the case when you call formatted(_:) on a BinaryInteger.
