# OSLogFloatFormatting

The formatting options for double and floating-point numbers.

## Declaration

```swift
@frozen struct OSLogFloatFormatting
```

Generating Log Messages from Your Code

## Overview

Overview An OSLogFloatFormatting structure encapsulates the formatting details for double and float values. Use the static fixed, hex, exponential, and hybrid structures to apply default formatting for floating-point values. You can also create new OSLogFloatFormatting structures that customize the rules for handling a leading plus sign, precision information, and more.
