Swift Question

How would you round up or down a Float to nearest even numbered integer in Swift 3?

I need a little help rounding up or down a float to the nearest even number in Swift.


32.86 would be closest to 32

33.86 would be closest to 34

If you want to round to the nearest even number, divide by 2, round and then multiply by 2:

let rounded = Int(round(value / 2.0)) * 2
