+## Syntax
+
+```pseudo
+round(num);
+```
+
+The `num` parameter must be a `double`,`float`, or `long double`. The return value will be an integer.
+In `halfway case` the number get round-off to the next closest integer.
-The `num` parameter must be a `double`,`float`, or `long double`. The return value will be an integer.
-In `halfway case` the number get round-off to the next closest integer.
+The `num` parameter must be a `double`,`float`, or `long double`. The return value will be an integer. If `num` is a halfway case where the decimal place is `.5` or higher, then the closest integer above `num` is returned.

+## Example 1
+
+```cpp
+double num = 4.5;
+double result;
+
+result = std::round(num);
+
+std::cout << "The result is " << result << "!\n";
+// Output: The result is 5!
+
+```

+## Codebyte Example
+
+The following example is runnable and rounds the halfway case away from zero:
+
+```codebyte/cpp
+#include <iostream>
+#include <cmath>
+
+int main() {
+  double num = 10.89;
+  double result;
+
+  result = std::round(num);
+
+  std::cout << "The result is " << result << "!\n";
+  // Output: The result is 11!
-  std::cout << "The result is " << result << "!\n";
-  // Output: The result is 11!
+  std::cout << "The result is " << result << "!\n";
-  std::cout << "The result is " << result << "!\n";
-  // Output: The result is 11!
+  std::cout << "The result is " << result << "!\n";
+}
