# Rounding Function

Is there a function that rounds float variables into
integers?  For example, flt = 2.83; round ( flt ); // flt will now be 3.  If there isn't, do you know how to make one?

//Hello Strider, you can write this code, it is very simple !!
// You can easily add 0.5 to the float number and assign it to
// An integer variable

#include <stdio.h>

void main(){
float f=2.83;
int i;

i=f + 0.5;    // Rounding function, just add 0.5 to the float number
// to be rounded

printf("\n%d",i);
}

//Sorry, last function would'nt work with negative numbers.
//This is the full version of round function. Just copy and //paste.. and it sould work.

#include <stdio.h>

int round(float f){
if (f>0) return int(f+0.5);    // Posotive number
else return int(f-0.5);        // Negative number
}

void main(){
float f;
int i;

f=2.83;
i=round(f);
printf("\n%d",i);

f=-2.83;
i=round(f);
printf("\n%d",i);
}

flt=floor(flt+0.5);

printf("%.0f",2.83);  //will print the rounded value (and should properly round to even for 2.5)
