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

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

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.
