Thread: [Dev-C++] Rounding off Floating Point numbers

Hello,

I would like to know if i have a value held in a float variable, how would I
fix the value to one decimal place???

I'm using Dev C++ Ver. 4 ..I know that to fix a floating point number I
first have to include the header <iomanip>, which i have already done....

I dont know wat to do next..Pliz Help...

thanks.

Ummmm did you want the answer for c or c++
here it is for C, try this out
=================================
#include <cstdlib>
#include <iostream>
float x=1;


using namespace std;

int main(int argc, char *argv[])
{

cout << "1/3 =" << x/3 << "\n";
 printf("1/3 = %.9f \n", x/3);
    system("PAUSE");
    return EXIT_SUCCESS;
}
==============================

printf("1/3 = %.9f \n", x/3);

the %.9f will give the answer to 9 decimal places


>From Eric

Attention Group

Is it possable to add a bit of class to the group my name is Eric, I am not too sure why the "bro" after all we are not in a Email group for coal miners .
If you would like me to help you with the C++ request I hope I enjoy taking out time to help you.  

While I am not up to speed to Per Westermark standards of C++, some times the someone elses answer come together with the question as I mainly get Email twice a day, The question to this thread came about midnight when I down loaded emails, I went to bed late so I could answer the question, I was not too sure if it was C or C++ or a hybrid question (C and C++ combined)         

Thankyou from Eric
