IMHO function calls also help readability. My version looks like this:
private let π = M_PI
private let d2r = π / 180 // degrees to radians adjustment
private let r2d = 180 / π // radians to degrees adjustments
private func degreesToRadians(degrees: Double) -> Double {
return degrees * d2r
}
private func radiansToDegrees(radians: Double) -> Double {
return radians * r2d
}
Yeah, "π = M_PI" wasn’t really needed.
