A Ruby library providing a Money class that encapsulates monetary amounts and currencies, storing values as integer cents to avoid floating-point errors. It includes currency metadata and APIs for exchanging money between currencies, with a companion money-rails gem for Rails integration.

Use cases

• handle money amounts in ruby without floating point errors
• convert between currencies in a ruby app
• store and compare monetary values in rails
• parse and format prices with currency metadata
• do arithmetic on monetary values safely
• manage currency exchange rates in an application

When to choose

• you're building a Ruby or Rails app that deals with prices, invoices, or payments
• you need exact integer-based monetary arithmetic across many currencies
• you want pluggable exchange-rate backends for currency conversion

When to avoid

• you need string-to-money parsing out of the box (use the companion monetize gem)
• your project isn't in Ruby
• you need a full accounting or billing system rather than a value object library
