Please describe how to reproduce this issue, and include links to screenshots if possible.

My code:

var randomNumberBetween0and19 = Math.floor(Math.rando

m() * 20);

function randomWholeNum() {

  // Only change code below this line.
  var rand = Math.random() * 10;
  return Math.floor(rand);
 // return Math.floor(Math.random() * 10); //works fine
//but above doesn't work
}

@raisedadead Yes, I have tested the code many times.

@ranaamritparth Just to confirm you have tested this :

var randomNumberBetween0and19 = Math.floor(Math.random() * 20);

function randomWholeNum() {
  // Only change code below this line.
  var rand = Math.random() * 10;
  return Math.floor(rand);
}

The original description has some code that can give a false positive.
