js获取整型数组最大值、最小值、平均值

---恢复内容开始---

let values = [];//数组（整型数字）

//获取数组最大值function arrMaxNum(arr){  var maxNum = null;  for (var i = 0; i < arr.length; i++) {    var item =parseInt(arr[i]);    if(item){      if(!maxNum){        maxNum = item;      }      item>maxNum ? maxNum =item : null;    }  };  return maxNum;};

//获取数组最小值（排除0）function arrMinNum(arr){

  var minNum = null;  for (var i = 0; i < arr.length; i++) {    var item =parseInt(arr[i]);    if(item){      if(!minNum){        minNum = item;      }      item<minNum ? minNum =item : null;    }  };  return minNum;};

//获取数组平均值（排除0）function arrAverageNum(arr){  var sum = 0;  var count = 0  for (var i = 0; i < arr.length; i++) {    var item =parseInt(arr[i]);    if(item){      sum += item;      count++;    }  };  return ~~(sum/count*100)/100;};
