Find Min/Max Of Array Of Integers

var min:Number;
var max:Number;

var numbers:Array =  new Array(3, 5, 2, 1, 4);

function findMin(array:Array):Number {
 min = array[0];
 for (var i = 0; i < array.length; i++) {
  if (array[i] < min) {
   min = array[i];
  }
 }
 return min;
}


function findMax(array:Array):Number {
 max = array[0];
 for (var i = 0; i < array.length; i++) {
  if (array[i] > max) {
   max = array[i];
  }
 }
 return max;
}


trace(findMin(numbers)); //Outputs 1
trace(findMax(numbers)); //Outputs 5
