Get double hours from double minute in Swift 2

Question

I'm using Swift 2. I have double myMinute and I want to convert it to double hours(myHours). How can I do it? My codes under below

let myMinute : Double = 62.0
let myHours  : Double = ?

I want to show with math example: myhours = 1.0

sorry don't understant but 1 min = 0.016666666h so to get hour = Double((myMinute * 0.016666666)) will give your hours — Iraniya Naynesh, Jul 27 '18 at 06:57

Found this here!

func minutesToHoursMinutes (minutes : Int) -> (hours : Int , leftMinutes : Int {
return (minutes / 60, (minutes % 60)) 
}

let timeTuple = minutesToHoursMinutes(minutes: 100)

timeTuple.hours  /// 1
timeTuple.leftMinutes /// 40

let roundedHours = Double(String(format: "%.1f", myHours)) @SwiftDeveloper – Daniel Lyon Jul 27 '18 at 07:38
I see in this answer you temporarily modified the code, though I don't understand the purpose of so many consecutive rollbacks. If you want to use the expanded version, feel free - it is in [the revision history](https://stackoverflow.com/posts/51552439/revisions). Also, the addition of some introductory/explanatory text as to why this answer solves the problem would be ideal. – halfer Mar 23 '20 at 10:58

The value should be 1.03 not 1.02 if you use the current value of minute (you can check with calculator) and it is a simple math, i think what you want beside the calculation is how to round the value to 2 decimal point. You should've made it clearer. This will do the work.

myHours = Double(round(myMinute / 60 * 100) / 100)
print(myHours)
