ios manipulators fixed() function in C++
The fixed() method of stream manipulators in C++ is used to set the floatfield format flag for the specified str stream. This flag sets the floatfield to fixed. It means that the floating-point values will be written in fixed point notations.
Syntax:
ios_base& fixed (ios_base& str)
Parameters: This method accepts str as a parameter which is the stream for which the format flag is affected.
Return Value: This method returns the stream str with internal format flag set.
Example 1:
#include <iostream>
using namespace std;
int main()
{
double x = 1.23;
cout.precision(5);
cout << "without fixed flag: "
<< x << endl;
cout << "with fixed flag: "
<< fixed << x << endl;
return 0;
}
|
Output:
without fixed flag: 1.23
with fixed flag: 1.23000
Example 2:
#include <iostream>
using namespace std;
int main()
{
double x = 1.0;
cout.precision(5);
cout << "without fixed flag: "
<< x << endl;
cout << "with fixed flag: "
<< fixed << x << endl;
return 0;
}
|
Output:
without fixed flag: 1
with fixed flag: 1.00000
Example 3:
#include <iostream>
using namespace std;
int main()
{
double x = 1.23e9;
cout.precision(5);
cout << "without fixed flag: "
<< x << endl;
cout << "with fixed flag: "
<< fixed << x << endl;
return 0;
}
|
Output:
without fixed flag: 1.23e+09
with fixed flag: 1230000000.00000
