The noshowpoint() method of stream manipulators in C++ is used to clear the showpoint format flag for the specified str stream. This flag displays the floating values in decimal only when they have a decimal values.
Syntax: 
 

ios_base& noshowpoint (ios_base& str)


Parameters: This method accepts str as a parameter which is the stream for which the format flag is to be cleared.
Return Value: This method returns the stream str with noshowpoint format flag set.
Example 1:
 

CPP 
// C++ code to demonstrate
// the working of noshowpoint() function

#include <iostream>

using namespace std;

int main()
{

    // Initializing the floating values
    double n1 = 10;
    double n2 = 20.0;

    cout.precision(5);

    // Using noshowpoint()
    cout << "noshowpoint flag: "
         << noshowpoint
         << n1 << endl
         << n2 << endl;

    return 0;
}

Output: 
noshowpoint flag: 10
20

 

Example 2:
 

CPP 
// C++ code to demonstrate
// the working of noshowpoint() function

#include <iostream>

using namespace std;

int main()
{

    // Initializing the floating values
    double n3 = 30.1223;

    cout.precision(5);

    // Using noshowpoint()
    cout << "noshowpoint flag: "
         << noshowpoint
         << n3 << endl;

    return 0;
}

Output: 
noshowpoint flag: 30.122
