Javascript always round up to X decimal places -


this question has answer here:

i need write function round up, either round 0, 1 or 2 decimal places, depending on if function passed 0, 1 or 2.

examples...

round 0 decimal places: 13.4178 = 14

round 1 decimal place: 13.4178 = 13.5

round 2 decimal places: 13.4178 = 13.42

i've found math.ceil rounds whole integer , to fixed() round or down, not up. there way round in way i've described above?

you use factor multiplication ten , power of wanted decimal count , round , adjust dot.

function up(v, n) {      return math.ceil(v * math.pow(10, n)) / math.pow(10, n);  }    console.log(up(13.4178, 0));  console.log(up(13.4178, 1));  console.log(up(13.4178, 2));

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
