in python, if you want to set the number of decimal point, you set it when you want to display like this:

print ("%.nf" %variable), whereas n is the number of decimal places that you want.

example:

result = 4/3
print ("%.1f" %result)

output=1.3

I saw in the other comment that you need to do it in C++.

Example program:

#include <iostream>
#include <iomanip>      //important for setprecision() !!!

using namespace std;

int main()
{
    double variable = 1.33333333333333333;
    cout<<setprecision(1)<<variable;
    
    return 0;
}

It will print out "1.3"

#include <stdio.h>

int main()
{
    float x;
    x=1.333333;
    printf("%.1f",x);
}

output:
1.3

suppose that you enter number a and b(double a,b)after cin>>a>>b;
we suppose that we entered  1 and 3.we want to find what is the period of this(1/3) fraction.answer of this program must be 3...
