deciaml place help

**artgirloc** · 12-03-2002

I am new at programming using C++. I am trying to write a program where ouput needs to be formatted to fit certain decimal place criteria. I am using Visual Basic C++. The folowing is just some of the program I wrote:

cout << fixed << showpoint;

then some equations, then,

cout << setprecision(0) << htInches << " inches" << endl;
cout << setprecision(2) << htMeters << " meters" <<endl;
cout << setprecision(0) << htCentimeters<< " centimeters" << endl;

I am racking my brain trying to get this to work. I have been all through the book also. No help at all. Any help I can get would be appreciated. Thank you in advance.

hmm are you using visual basic or visual c++...hehe..thats my first question..but it seems like you are using visual c++

here is code:

Code:

#include <iostream>

using namespace std;

int main()
{
	float x = 1.2345f;

	cout.setf(ios::fixed);
	cout.precision(3);
	cout << x << endl;

	return 0;

}

well it should output only 1.235 since precision is set to 3 it will only out 3 digits after the decimal which is the 4 but it's rounding it up to a 5 because of the 5. hope that helps
