# UInt128/Int128

A 128-bit unsigned/signed integer implementation with optimized multiplication, division, and string conversions.

The user interface has been changed to be in sync with Apple's unreleased version of the UInt128/Int128.

This package is usually around ten times faster than other UInt128 implementations and roughly the same

speed as Apple's implementation. If you find something faster, please let me know.

This package now supports `StaticBigInt`. Unfortunately, this means you need

to have one of following configurations (or higher) 

1. macOS 13.3+, 

2. iOS 16.4+, 

3. macCatalyst 16.4+, 

4. tvOS 16.4+,

5. watchOS 9.4+

If you don't have these configurations, you need to use a previous release of

UInt128/Int128.

## Installation

This library includes Swift Package support out of the box.

Reference this git repository via XCode to install as a Package.

  - Warning: This interface uses different initializers than earlier versions.

You can also manually copy over the `Sources/(U)Int128.swift` files into your project

and it should work great. This file split duplicates Apple's UInt128 and Int128

files. Note: Some common utilities are located in the `Common.swift` file which

you'll also need if copying to your project.
