Half

Half is a lightweight framework containing a Swift implementation for a half-precision floating point type for iOS, macOS, tvOS, and watchOS.

Installation

Half is available through CocoaPods, Carthage and the Swift Package Manager.

To install via CocoaPods, simply add the following line to your Podfile:

pod 'Half'

To install via Carthage, simply add the following line to your Cartfile:

github "SomeRandomiOSDev/Half"

To install via the Swift Package Manager add the following line to your Package.swift file's dependencies:

.package(url: "https://github.com/SomeRandomiOSDev/Half.git", from: "1.0.0")

Usage

First import Half at the top of your Swift file:

import Half

After importing, use the imported Half type excatly like you'd use Swift's builtin Float, Double, or Float80 types.

let value: Half = 7.891
let squareRoot = sqrt(value)

...

NOTE

• [SE-0277] added support for a native Float16 type starting with Swift 5.3, therefore, this library is no longer recommended for projects using Swift 5.3 or later and this will likely be deprecated sometime in the future.
