noshowpoint
Displays only the whole-number part of floating-point numbers whose fractional part is zero.
ios_base& noshowpoint(
ios_base& _Str
);
Parameters
- _Str
A reference to an object of type ios_base, or to a type that inherits from ios_base.
Return Value
A reference to the object from which _Str is derived.
Remarks
noshowpoint is on by default; use showpoint and precision to display zeros after the decimal point.
The manipulator effectively calls _Str.unsetf(ios_base::showpoint), and then returns _Str.
Example
// ios_noshowpoint.cpp
// compile with: /EHsc
#include <iostream>
int main( )
{
using namespace std;
double f1= 5.000;
cout << f1 << endl; // noshowpoint is default
cout.precision( 4 );
cout << showpoint << f1 << endl;
cout << noshowpoint << f1 << endl;
}
5 5.000 5
