By subtracting 0.5 from the value returned by Math.random (), you are essentially changing the range of the returned value. For the smallest value that Math.random () returns (0) you will get -0.5. And for the maximum value (0.9999…) you will get (0.4999…).

When you floor the number you would get 11 NOT 10 (although I understand this would be a rare case). I was wondering can Math.random() = 1 or 0? console.log(score);
WebWhy does the Math.random function return a double in the range [0, 1), instead of other intervals in Java? Generating numbers between 0 and 1 allows you to scale directly to other ranges. If you need the range 0 to 256, simply multiply the result by 256. So from a practical standpoint, the range [0,1) is the most convenient.
