C++ :: How To Do Precision With Ostrstream
Jul 25, 2013Setting precision for the float value .. E.g..
ostrstream out;
float fvalue = 2.7889
out << fvalue;
if I take the value of out.str() i should be able to get 2.78 only.

Visual C++ :: Constantly Calling Ostrstream - Private Member Access Violation
Sep 22, 2014Code:
std::ostrstream oss;
oss << "path for " << unit << "
" << path;
puts(oss.str());
[Code] .....
Today, I just received this new fresh error, I was constantly using them, but just come to know it is a private access violation as the last error of my program. Did I use it in the wrong way?
C++ :: Set Precision With Floating Point Numbers?
Feb 25, 2014I'm displaying a table of floating point numbers with setprecision(5). If the number is "1.25" it will display "1.2500" which is what I want. However, if the number is "0.25" it will display "0.25000"
How can I make numbers with a base number of zero display properly?
C :: Convert Floating Point Scientific Precision

C :: Getting Correct Float Value Without Having To Write In Width / Precision
Jul 16, 2014I have this
Code:
#include <stdio.h>
int main() {
float number1, number2;
printf("Enter two numbers separated by a comma ");
scanf("%f,%f", &number1, &number2);
[Code] ....
When it prints the values, it prints them as I want. the problem is, what happens when someone puts in values with different width and precision? Here I had to write in the width and precision to display the values that are specified in the book. but what happens when someone puts in something that doesn't have those width/precision?
I end up with a lot of zeros after the number. initially I got 24.000000 (zeros are not accurate amount) I needed to show just 24. (with the decimal)
So I included %2.0f which gave me 24 (without the decimal point) what if some one put in 24.556. I got 25 as a result.
Does the width mean how many numbers in total including the decimal point and that is a minimum?
C++ :: How To Install High Precision Arithmetic Library
Jan 12, 2013One of my programs I recently created, needs higher precision then what doubles can provide. So I am wondering how I install a library like this [URL] .... I don't quite understand exactly how to install them. Im using visual studio 2012 ultimate right now!
