double x = getX();
int i = (int) x;
// Good Idea
// Not a Bad Idea
int i = static_cast<int>(x);
```
Additionally the C++ cast style is more visible and has the possibility to search for.
But consider refactoring of program logic (for example, additional checking on overflow and underflow) if you need to cast `double` to `int`. Measure three times and cut 0.9999999999981 times.
