Random with Min, Max

How would I generate an integer that is between -1 and 1 with Math.random()?

Code:

---

function Random(min, max) {
  return (min + (max - min) * Math.random());
};

  //Logic Test: Math.random() = 0
  // min + (0) = min
  // Logic Test: Math.random = 1
  // min + (max - min) = max

---

Thanks, the function is similar to what I found googling.

Anyways, I think I figured out the one-liner way to do it, which is what I wanted.

Code:

---

var random = Math.random() * -2 + 1;

---

Works well.

That's exactly the same, you realise. Just replace min with 1 and max with -1 :D
