I have a general question for situations where you need to change the type of a variable.

Let's say I have a float variable a but want it as an int, what I always did is

float a = 0.5;
int RoundedA = int(a);

However now I learned you should actually do it like:

float a = 0.5;
int RoundedA = (int)a;

The result of both is the same, so is it just a different style and it does the same, or is actually something different happening? And if so is there any performance difference between those two?

BTW your casts truncate, they don't round. – Mat Jun 02 '22 at 11:23

For the OC++D, you should do it like `int RoundedA = static_cast(a);` – Eljay Jun 02 '22 at 11:39
