Truncated floating point with C++ streams

[dude_1967]

Hello,

Can anyone please tell me the appropriate flag combination for formating truncated floating point values using C++ streams. I do not want any rounding.

Thanks 1*10^6 (thanks a million).

Chris.

Code example with questions within the comments:

#include <iostream>
#include <iomanip>
using namespace std;

int main(int argc, char* argv[])
{
  // Have nine nines.
  double d = 0.999999999;

  // Want eight nines but don't get it.
  // How do I get the truncation?
  // Is it possible using streams?
  cout << std::setprecision(8) << std::fixed << d << endl;

  return 1;
}
