#include <iostream>

#include "fmt/printf.h"

#pragma comment(lib, "fmtd.lib")

int main()
{
    double someVerySmallValue = 7.2809479766055470e-15;

    printf("%.4lf\n", someVerySmallValue);

    fmt::printf("%.4lf\n", someVerySmallValue);

    printf("Done\n");
}

Produces the following on x86 MSVC 2019

0.0000
0.00001
Done

Weirdly in my actual project code I see 0.00000 when I would expect 0.0000
