round double to n decimal places c++
float roundoff(float value, unsigned char prec)
{
float pow_10 = pow(10.0f, (float)prec);
return round(value * pow_10) / pow_10;
}
auto rounded = roundoff(100.123456, 3);
// rounded = 100.123;
round double to n decimal places c++
value = round( value * 100.0 ) / 100.0; // 2 decimal places
value = round( value * 1000.0 ) / 1000.0; // 3 decimal places
round double to 2 decimal places c++
double d = 0.12345;
std::cout.precision(2); // for accuracy to 2 decimal places
std::cout << d << std::endl; // 0.12
how to make floats output with 2 decimals c++
#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;
}
get number round off to two decimal places c++
float a,b,c,d,sum;
cin>>a>>b>>c>>d; // reading decimal values
sum=(a*b*c*d);
sum=round(sum*100)/100; // here it is for 2 decimal points
if((float)sum < (float) 9.58)
cout<<"YESn";
else
cout<<"NOn";
