# 10.00 USD
ten_dollars = Mint.money(10, 'USD') #=> [USD 10.00]
ten_dollars.to_i #=> 10
ten_dollars.currency_code #=> "USD"
# Comparisons
ten_dollars = Mint.money(10, 'USD')
ten_dollars == Mint.money(10, 'USD') #=> true
ten_dollars == Mint.money(11, 'USD') #=> false
ten_dollars == Mint.money(10, 'EUR') #=> false
ten_dollars.eql? Mint.money(10, 'USD') #=> true
ten_dollars.hash == Mint.money(10, 'USD').hash #=> true
# Format (uses Kernel.format internally)
price = Mint.money(9.99, 'USD')
price.to_s #=> "$9.99",
price.to_s(format: '%<amount>d') #=> "9",
price.to_s(format: '%<symbol>s%<amount>f') #=> "$9.99",
price.to_s(format: '%<symbol>s%<amount>+f') #=> "$+9.99",
(-price).to_s(format: '%<amount>f') #=> "-9.99",
# Format with padding
price_in_euros = euro.money(12.34, 'EUR')
price.to_s(format: '--%<amount>7d') #=> "-- 9"
price.to_s(format: ' %<amount>10f %<currency>s') #=> " 9.99 USD"
(-price).to_s(format: ' %<amount>10f') #=> " -9.99"
price_in_euros.to_s(format: '%<symbol>2s%<amount>+10f') #=> " € +12.34"
# Json serialization
price.to_json # "{"currency": "USD", "amount": "9.99"}
# Allocation and split
ten_dollars.split(3) #=> [[USD 3.34], [USD 3.33], [USD 3.33]]
ten_dollars.split(7) #=> [[USD 1.42], [USD 1.43], [USD 1.43], [USD 1.43], [USD 1.43], [USD 1.43], [USD 1.43]]
ten_dollars.allocate([1, 2, 3]) #=> [[USD 1.67], [USD 3.33], [USD 5.00]]
# Numeric refinements
uning Mint
1.dollar == Mint.money(1, 'USD') #=> true
3.euros == Mint.money(2, 'EUR') #=> true
4.mint('USD') == 4.dollars #=> true
4.to_money('USD') == 4.dollars #=> true
