* Task
Implement the following rounding function that rounds a 64-bit floating point number (type `double`) to the nearest 32-bit integer (type `int`). You may assume that the type `double` complies with the IEEE standard 754. The function is only required to work correctly if the nearest integer is in the value range of the type `int`, otherwise, the return value of the function is undefined.
Implement the following rounding function that rounds a 64-bit floating point number (type =double=) to the nearest 32-bit integer (type =int=). You may assume that the type =double= complies with the IEEE standard 754. The function is only required to work correctly if the nearest integer is in the value range of the type =int=, otherwise, the return value of the function is undefined.
**Note: Usage of library rounding functions (standard or others) is not allowed.**

Write your solution in `rounding.h`.
Write your solution in =rounding.h=.
/Hint/: In `C++`, when you convert a `float` or `double` to an `int`, the fractional part gets cut off (truncated). Think about how you can use the truncated number to solve the exercise.
