Rounding off a value means replacing it by a nearest value that is approximately equal or smaller or greater to the given number.

y = (int)(x + 0.5); here x is any float value. To roundoff, we have to typecast the value of x by using (int)

Example:

#include

int main ()

{

  float x = 2.6;

  int y = (int)(x + 0.5);

  printf ("Result = %d\n", y );

  return 0;

}

Result : 3
