Decimal: Arbitrary precision decimal arithmetic.

defmodule Billing.Invoice do defstruct ~w( id title number seller client issued_on payment_due_date articles total payment_information )a @type t :: %__MODULE__{ id: pos_integer(), title: String.t(), number: String.t(), seller: Company.t(), client: Company.t(), issued_on: DateTime.t(), payment_due_date: DateTime.t(), number: String.t(), articles: [Article.t()], total: Total.t(), payment_information: PaymentInformation.t() } defmodule Company do defstruct ~w( name logo address zip_code city country registration_number vat_number )a @type t :: %__MODULE__{ name: String.t(), logo: String.t(), address: String.t(), zip_code: String.t(), city: String.t(), country: String.t(), registration_number: String.t(), vat_number: String.t() } end defmodule Article do defstruct ~w( details qty unit_price vat total_excl_vat total )a @type t :: %__MODULE__{ details: String.t(), qty: integer(), # I recommand using https://hexdocs.pm/decimal or # https://hexdocs.pm/money in a real project unit_price: float(), vat: float(), total_excl_vat: float(), total: float() } end defmodule Total do defstruct ~w( total_excl_vat vat_amount total )a @type t :: %__MODULE__{ # I recommand using https://hexdocs.pm/decimal or # https://hexdocs.pm/money in a real project total_excl_vat: float(), vat_amount: float(), total: float() } end defmodule PaymentInformation do defstruct ~w( bic iban reference )a @type t :: %__MODULE__{ bic: String.t(), iban: String.t(), reference: String.t() } end end

Cloud getting started guide

I also recommend getting to know the project Getting Started with ScyllaDB Cloud which demonstrates the use of ScyllaDB in general, but, delving a little deeper into the use of ScyllaDB's own platform for managing your Cloud clusters, cool isn't it?
