JS Arrotondare Superiore Numero

 // value is the value to round
 // places if positive the number of decimal places to round to
 // places if negative the number of digits to round to
 function roundTo(value, places){
     var power = Math.pow(10, places);
     return Math.round(value * power) / power;
 }
 var myNum = 10000/3;    // 3333.3333333333335
 roundTo(myNum, 2);  // 3333.33
 roundTo(myNum, 0);  // 3333
 roundTo(myNum, -2); // 3300
