Max and min in an array of Float in Swift

Question

According to this answer, to obtain the maximum of an array we can do:

let nums = [1, 6, 3, 9, 4, 6];
let numMax = nums.reduce(Int.min, { max($0, $1) })
         


        

Answer 1

The solution given here https://stackoverflow.com/a/24161004/1187415 works for for all sequences of comparable elements, therefore also for an array of floats:

let floats: Array = [2.45, 7.21, 1.35, 10.22, 2.45, 3]
let numMax = maxElement(floats)

maxElement() is defined in the Swift library as

/// Returns the maximum element in `elements`.  Requires:
/// `elements` is non-empty. O(countElements(elements))
func maxElement(elements: R) -> R.Generator.Element
