C Program for Rounding off any Floating-point numbers

In stead of using round( ), roundf( ), ceil( ), floor( ) to round-off any numbers, this is the best manipulating way.

#include<stdio.h>

#include<conio.h>

void main()

{

  float i=6.8;

  int k;

  float r;

  k=i;

  r=((i-k)>=0.5)?k+1:k;

  printf("Rounding of %f is %f",i,r);

  getch();

}

OUTPUT:
