round to integer

[anitai]

I can´t find any function for doing this.Is there any fast,simple way of doing it?

Thank you.

For positive numbers it is simple:

double y = 1.234;
int x = reinterpret_cast<int>(y + 0.5);

For negative numbers you have to decide if you are rounding DOWN (a more negative number) or TOWARDS zero. That will change the sign....

I don't know if there is any function, but an easy way to do it is this:

double number = ...;

int round = (number<0) ? (int)(number-0.5) : (int)(number+0.5);

I hope this helps you.
