const result = Money.create(100);

// Check if a value is a valid monetary amount

// Divide one monetary value or Money object by another
const quotient = Money.divide(product, 4);

// Round down the monetary value to the nearest integer
const floorValue = quotient.floor();

// Round up the monetary value to the nearest integer
const ceilValue = quotient.ceil();

// Calculate compound interest based on the provided rate and periods
const interest = Money.compoundInterest(5, 10);

// Generate a random monetary value within the specified range

// Convert the current Money value to another currency using the provided exchange rate
const convertedAmount = amount.convertTo(2);

// Generate a formatted string representing the monetary value in a specific currency and locale
const formattedAmount = amount.coin('USD', 'en-US');

console.log(formattedAmount);
// Output: $100.00 (assuming 100 is the amount in USD)
