use fish_printf::{printf_c_locale, ToArg, FormatString};
use std::fmt::Write;

let mut output = String::new();
let fmt: &str = "%0.5g";  // Example format string
let mut args = [123456.0.to_arg()];

let result = printf_c_locale(&mut output, fmt, &mut args);

assert!(result == Ok(10));
assert_eq!(output, "1.2346e+05");
