Re: [swift-evolution] [Pitch] Angle Type

This could work, but you’re also giving up all the nice Numeric and FloatingPoint conformances when you use this,, all of a sudden adding two angles together isn’t let γ = α + β, it’s γ = Angle.radians(α.radians + β.radians). just no. at the risk of blowing up the scope of this idea, dedicated

Re: [swift-evolution] [Pitch] Angle Type

I do a lot of geometry and spherical-related work and i have never found an Angle type to be worth having. Always use radians. It’s what sin() and cos() take, it’s what graphics APIs like Cairo expect, it’s what graphics formats like SVG use. plus,, do you *really* want to be case-branching on

Re: [swift-evolution] [Pitch] Angle Type

An Angle type already exists in Foundation; see Measurement. You could add some convenience methods in an extension pretty easily. import Foundation typealias Angle = Measurement extension Measurement where UnitType == UnitAngle { var sine: Double { let radians = self.converted(to:

Re: [swift-evolution] [Pitch] Angle Type

I would like to see a full Geometry implementation but I don't think it should be part of the standard library. I've kicked around some ideas here: * https://gist.github.com/erica/8cb4b21cf0c429828fad1d8ad459b71b *
