do you mean static_cast has compile time benifits as compared to using the
other casting method?

Okay. Conceded. Personally, I prefer making sure the compiler knows
exactly what I mean and I never rely on implicit rules. It is a habit
I've learned over the years after getting bitten by numerous bugs. So I
will always prefer:
double result = ((double)4) / ((double)5);
OR
double result = 4.0 / 5.0;

I've read enough on static_cast to know it doesn't do much of anything
different from C-style casting for fundamental data types (int, double,
char, float, short, long, unsigned, signed). I use static_cast for
classes and other more complex types though because there ARE
compile-time benefits there.
