[Pitch] Angle Type

Hi Evolution, I would really like to see Swift gain an Angle type in the standard library. Every time I have to deal with an angle in an api, I have to go figure out the conventions for that call. Is it in degrees? Is it in radians? What if it is in radians, but I want to think about it in degrees? I ended up writing an Angle type for my own code a few years back, and I have to say it is really wonderful. It has greatly simplified my graphics work. It takes a lot of mental load off of my …

TrigonometricFloatingPoint/MathFloatingPoint protocol?

How would people feel about adding a protocol protocol MathFloatingPoint:FloatingPoint {     func sin() -> Self     func cos() -> Self     func tan() -> Self     func asin() -> Self     func acos() -> Self     func atan() -> Self     func ln() -> Self     func log(base:Self) -> Self     func pow(exponent:Self) -> Self     func exp() -> Self } to the standard library? Float and Double would then be made to conform by default using Swift implementations instead of having to import G…
