use steel_cent::currency::USD;
use steel_cent::formatting::{us_style, uk_style, france_style};

let price = Money::of_major_minor(USD, 19, 95);

let convenience_charge = Money::of_major(USD, 6);
let fees = shipping_and_handling + convenience_charge;
let discount: f64 = 1.0 - 0.2; // 20% off
let discounted_price = price * discount;
let total = discounted_price + fees;

assert_eq!(Money::of_major_minor(USD, 15, 96), discounted_price);
assert_eq!(Money::of_major_minor(USD, 31, 96), total);
assert_eq!((price * discount) + shipping_and_handling + convenience_charge, total);

assert_eq!("total: $31.96",
           format!("total: {}", us_style().display_for(&total)));
