Requirements

GMP

Currently libgmp.a 6.0.0a is included. You can rebuild it using the GMP iOS Builder.

Carthage

Add the following to your Cartfile:

 github "NeoTeo/SwiftGMP"

Then, in the root of your project, type: carthage update

You will then need to add frameworks to your own Xcode project:

1. Select your target's Build Phases tab.
2. Select the Link Binary With Libraries, click the + and then Add Other... buttons.
3. Navigate to the Carthage/Build/Mac directory in your project root and select the SwiftGMP.framework.
   In case of a code signing error, select the target's Build Settings tab make sure the "Code Signing Identity" is either a valid identity or "Don't Code Sign".

For more information on how to install via Carthage see the README.

Swift 2+

For Swift 3 builds you may have to modify your xcode location. You can do this by running sudo xcode-select --switch /Applications/Xcode-beta.app/Contents/Developer/ or setting it from Xcode -> Preferences -> Locations -> Commmand Line Tools

Usage

A full set of examples can be found in our test suite.

import SwiftGMP

let s2d = SwiftGMP.GMPDouble("12356789123456789.9876")
let d2d = SwiftGMP.GMPDouble(12345.678)
print(String(s2d + d2d))
