A Big Ints library written in pure Swift 4.

This project provides integer types of arbitrary width implemented in 100% pure Swift.

Now only one integer type is included - BigUInt. It is the Swift struct with copy-on-write value semantics, and it can be used much like any other integer type.

The library provides implementations for the most useful functions on big integers, including:

• All functionality of Comparable and Hashable

• ALL arithmetic operators: +, -, *, /, %, +=, -=, *=, /=, %=

• Bitwise operators: ~, |, &, ^, |=, &=, ^=, plus the following read-only properties:

• width: the minimum number of bits required to store the integer,

• trailingZeroBitCount: the number of trailing zero bits in the binary representation,

• leadingZeroBitCount: the number of leading zero bits (when the last digit isn't full),

• Shift operators: >>, <<, >>=, <<=

• Radix conversion to/from Strings and big integers.

The library needs to be 100% unit test coveraged.

TinyBigInt can be used, distributed and modified under the MIT license.

TinyBigInt 1.0.0 requires Swift 4.

BigInt deploys to macOS 10.10, iOS 9, watchOS 2 and tvOS 9.

Setup instructions:

• Swift Package Manager: Although the Package Manager is still in its infancy, BigInt provides experimental support for it. Add this to the dependency section of your Package.swift manifest:

  .Package(url: "https://github.com/matterinc/TinyBigInt.git", from: "1.0.0")

• CocoaPods: Put this in your Podfile:

  pod 'TinyBigInt', '~> 1.0'
