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
