$money = Money::of(50, 'USD'); // USD 50.00
$money = Money::of('19.9', 'USD'); // USD 19.90
$money = Money::of('123.456', 'USD'); // RoundingNecessaryException
$money = Money::of('123.456', 'USD', roundingMode: RoundingMode::Up); // USD 123.46
$money = Money::ofMinor(1234, 'USD'); // USD 12.34

$money = Money::of(50, 'USD');

echo $money->plus('4.99'); // USD 54.99
echo $money->minus(1); // USD 49.00
echo $money->multipliedBy('1.999'); // USD 99.95
echo $money->dividedBy(4); // USD 12.50

$cost = Money::of(25, 'USD');
$shipping = Money::of('4.99', 'USD');
$discount = Money::of('2.50', 'USD');

echo $cost->plus($shipping)->minus($discount); // USD 27.49

$oneEuro = Money::of(1, 'EUR');

$oneEuro->isEqualTo(Money::of(1, 'EUR')); // true
$oneEuro->isEqualTo(Money::of(2, 'EUR')); // false
$oneEuro->isEqualTo(Money::of(1, 'USD')); // CurrencyMismatchException
