我正在根据公式计算两个数字之间的百分比增长

newnumber - oldnumber
----------------------- * 100
  oldnumber




var oldNumber = 33, newNumber = 40;

var percent = newNumber - oldNumber;

var percent2 = percent/oldNumber;

var PercenIncr = Math.ceil(percent2*100).toFixed(2);

alert(PercenIncr)

我可以在一行中完成所有这些操作吗?

最佳答案

尝试这个



var oldNumber = 33, newNumber = 40;
var PercenIncr = Math.ceil(((newNumber - oldNumber)/oldNumber)*100).toFixed(2);
alert(PercenIncr)
