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<<"YES\n";
else
cout<<"NO\n";round up 2 digits float c++
#include <iostream>
using namespace std;
float round(float var)
{
// 37.66666 * 100 =3766.66
// 3766.66 + .5 =3767.16 for rounding off value
// then type cast to int so value is 3767
// then divided by 100 so the value converted into 37.67
float value = (int)(var * 100 + .5);
return (float)value / 100;
}
int main()
{
float var = 37.66666;
cout << round(var);
return 0;
