sorry i have new fix and more easy:

int main()
{
    using namespace std;
    double n,v,k,m,k1, r;
    n = 100,67; //
    v = 4.26; //
    m = 20; //
    
    k = n – m;
    r = k / v;
    
    
    cout << "NOT Rounded= " <<  r << endl;     cout << "Rounded= " <<  round ( r )<< endl;               system ("pause");     return 0;

Note: Always name a float bacon1

if you want it to round as we normally do, then do Floor(number+0.5), and that will round it up if it is .5 or above, or down if it’s .4 or below. You can also do Ciel(number-0.5) but who likes subtraction?
For example: you have 3.5 this would round to 4 right? Well, let’s plug it in. Floor(3.5+0.5) = Floor(4.0) = 4.0.
And for 3.1? Floor(3.1+0.5) = Floor(3.6) = 3.0

How come I get a compiler error? I wrote the exact same code as you did.
Yet I keep getting the undefined reference to both floor and ceil.

coz, why the heck not ? and @bucky, what happened to the chick ? your friend’s hot friend ?

-1 for saying that the computer isn’t as smart as smart. as stated by Sebastian, it can round to the nearest whole number. Even if round wasn’t available, you could use floor(float + 0.5) for positive values.

There is a round() function in the math.h library that does normal rounding. You don’t have to specify if you want to round up or down.

flour = flout sorry and after 45.8494 is ; =45.8494;

Ceil stands for ceiling, like a roof.

Idk how you make coding interesting/funny but you do

Can someone tell me how to have these #include texts in my programs durable?

how about i want to rounding up to nearest 0.5?
for example:
13.14 => 13.50
13.61 => 14.00
13.50 => 13.50

Bucky why do you use floats instead of doubles?

Actually there is a Another Way to do this just type .0 in between % and f (%.0f) and this will Round the Numbers

Hey guys here is my code, but I want to know if there is a command that allows to test the second number after the comma in a number ( ex: 9.6 : test the “6” if it’s above or less than 5 ). that will make it more efficient:

int main()

{
float num1 = 9.4;

if(num1>=9.5){
printf(“num1 is %.2f n”, ceil(num1));

}else{
printf(“num1 is %.2f n”, floor(num1));
}

return 0;
}

I still cant debug my problem in greedy(program) of the value 4.2. what am I missing?
