Is there any mechnisam for roundoff float numbers in c++

[bush123]

Hello guys..i am working on a program where in calculation if i got for example 14.6 i have to round off it to 15..how to do this??

In a simple case, something like this would suffice:

double f = 14.6 ;
int  n = f + 0.5 ;

try:

#include<iostream>
#include<iomanip>

using namespace std;
int main()
{
  float f = 27.34576;
  cout<<"\n\n";
  cout<<"f: =  "<<f;
  cout<<"\nf rounded up: = "<<ceil(f);
  cout<<"\nf with setprecision(5): = "<<setprecision(5)<<f;
  cout<<"\n";
  return 0;

}

/*f: =  27.3458
f rounded up: = 28
f with setprecision(5): = 27.346 note the 6 here*/
