Rounding Double

Playground demonstration for rounding a double number to N places.

How can you use it?

Make it a part of your own extension ⚙

import Foundation

extension Double {
    /// Rounds the double to N number of decimal places
    mutating func round(to places: Int) -> Double {
        let divisor = pow(10.0, Double(places))
        return Darwin.round(self * divisor) / divisor
    }
}

There are multiple ways to achive this but I prefer this way! ✏
