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

Initializes an attributed byte count format style.

## Declaration

```swift
init(style: Measurement<UnitType>.AttributedStyle.ByteCount.Style, allowedUnits: Measurement<UnitType>.AttributedStyle.ByteCount.Units, spellsOutZero: Bool, includesActualByteCount: Bool, locale: Locale)
```

## 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.
