std::fixed



          

std::fixed - Fixed Floating-point notation : It write floating-point values in fixed-point notation. The value is represented with exactly as many digits in the decimal part as specified by the precision field (precision) and with no exponent part.
   
   Defined in header <ios>
   std::ios_base& fixed( std::ios_base& str );

For Example:
//c++ program
//std::fixed
#include<iostream>  
using namespace std; 
int main(){ 
    // Initializing floating point variable 
    double a=4.223234232; 
    double b=722.0; 
  
    // Specifying precision 
    cout.precision(4); 
      
    // Printing normal values 
    cout<<"Normal values : a="<<a<<" "<<"b="<<b<<endl; 
      
    // Printing values using fixed ( till 4 ) 
    cout<<"Values using fixed"<< std::fixed<<endl;; 
    cout<<"a="<<a<<" "<<"b="<<b<<endl;  

    return 0; 
} 
   
  Output:
   Normal values : a=4.223 b=722
   Values using fixed
   a=4.2232 b=722.0000
