converting double to int

Hi everyone...

I was wondering if there is a way to convert a double value to an int value.

What i'm trying to do is to find the ceiling of an integer divided by 2.

Code:

---

#include<math.h>

int num = 5;

double value = ceil(5/2);

//int ceiling = value            ///I want to do this.....

---

Thank you!!

That's legal in C++. The compiler probably issues a warning, which you can get rid of by making the cast explicit.

int ceiling = (int) value;

But beard in mind that 4.99999 will yield 4 in this situation. There's no rounding - just cutting off the decimal portion.

You could add .5 to the double named value and use floor() to round off, or subtract .5 and use ceil().
4.9 + .5 = 5.4, which will floor() to 5.0
Even if you ceil() or floor() a double, it's not an int; the value is 2.0, or 3.0, or whatever, not 2 or 3. Use the cast like SilentStrike said.

look in the function list at cprogramming theres one to round it off then turn it into an int
