Wrong output for fixed-precision floating-point format

[jk-jeon]

Please look at the following code:

#include <iostream>
#define FMT_HEADER_ONLY 1
#include "fmt/format.h"

int main () {
 std::cout << fmt::format("{:.1e}", 1e-34);
}

The output of the code is

1.00e-34

but the expected output is

1.0e-34

So fmt is putting one more 0. The same is happening when the precision is set to larger values. It seems that this issue only happens for certain floating-point inputs.

Good catch, thanks. Fixed in a18b3fb.
