## Printing float values with fixed number of decimal places through cout in C++

Here, we will learn how to print float value with fixed number of decimal places using cout in C++ program?

cout prints a floating pointer number with a maximum of 6 decimal places (some compilers may print 5 decimal places) by default (without trailing zeros).

Consider the give statement

``````int main()
{
float x=10.38989445f;
cout<<x<<endl;

return 0;
}
``````

The output would be 10.3899

## How to print float numbers with fixed number of decimal places?

We can print float numbers with fixed number of decimal places using std::fixed and std::setprecision, these are the manipulators, which are defined in the iomanip header file.

Syntax of setprecision

`std::setprecision(int n)`

Here, n is the number of digits after the decimal point (number of decimal places)

Consider the given example

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

int main()
{
float x=10.3445f;

cout<<fixed<<setprecision(5)<<x<<endl;
cout<<fixed<<setprecision(2)<<x<<endl;
cout<<fixed<<setprecision(3)<<x<<endl;
cout<<fixed<<setprecision(0)<<x<<endl;

return 0;
}
``````

Output

```10.34450
10.34
10.344
10```
