+title: Generate Random Whole Numbers within a Range
+challengeType: 1

+
+# --description--
+
+You can generate a random whole number in the range from zero to a given number. You can also pick a different lower number for this range.
+
+You'll call your minimum number `min` and your maximum number `max`.
+
+This formula gives a random whole number in the range from `min` to `max`. Take a moment to read it and try to understand what this code is doing:
+
+```js
+Math.floor(Math.random() * (max - min + 1)) + min
+```
+
+# --instructions--
+
+Create a function called `randomRange` that takes a range `myMin` and `myMax` and returns a random whole number that's greater than or equal to `myMin` and less than or equal to `myMax`.
+
+# --hints--
+
+The lowest random number that can be generated by `randomRange` should be equal to your minimum number, `myMin`.
+
+```js
+assert(
+  (function () {
+    if (typeof randomRange !== 'function') {
+      return false;
+    }
+
+    var calcMin = 100;
+    for (var i = 0; i < 100; i++) {
+      var result = randomRange(5, 15);
+      calcMin = Math.min(calcMin, result);
+    }
+
+    return calcMin === 5;
+  })()
+);
+```
+
+The highest random number that can be generated by `randomRange` should be equal to your maximum number, `myMax`.
+
+```js
+assert(
+  (function () {
+    if (typeof randomRange !== 'function') {
+      return false;
+    }
+
+    var calcMax = -100;
+    for (var i = 0; i < 100; i++) {
+      var result = randomRange(5, 15);
+      calcMax = Math.max(calcMax, result);
+    }
+
+    return calcMax === 15;
+  })()
+);
+```
+
+The random number generated by `randomRange` should be an integer, not a decimal.
+
+```js
+assert(randomRange(0, 1) % 1 === 0);
+```
+
+`randomRange` should use both `myMax` and `myMin`, and return a random number in your range.
+
+```js
+assert(
+  (function () {
+    if (
+      __helpers.removeJSComments(code).match(/myMax/g).length > 1 &&
+      __helpers.removeJSComments(code).match(/myMin/g).length > 2 &&
+      __helpers.removeJSComments(code).match(/Math.floor/g) &&
+      __helpers.removeJSComments(code).match(/Math.random/g)
+    ) {
+      return true;
+    } else {
+      return false;
+    }
+  })()
+);
+```

+function randomRange(myMin, myMax) {
+  return Math.floor(Math.random() * (myMax - myMin + 1)) + myMin;
