Fixed Decimal Precision [duplicate]

Question

I am currently using

std::cout.precision(5);

to set the decimal precision of my outputs. However, I would rather have my output ALWAYS output 5 decimal places (right now it won't show 0's). How would I change my code to reflect this?

Answer 1

You are looking for std::fixed together with std::setprecision.

#include <iomanip>
#include <iostream>
double f =1.1;
std::cout << std::fixed;
std::cout << std::setprecision(5) << f << std::endl;

stdout

1.10000
